Sourcing 3-Chloro-1-(4-Octylphenyl)propan-1-one: Bulk Supply & Quality
Technical Specifications and Purity Grades for 3-Chloro-1-(4-octylphenyl)propan-1-one
In the procurement of 3-Chloro-1-(4-octylphenyl)propan-1-one, often referred to as a Fingolimod Intermediate or Chlorooctylphenyl Ketone, the primary technical consideration is the purity grade required for the intended synthesis route. Industrial buyers typically encounter two main grades: technical grade (≥95%) and pharmaceutical grade (≥98%). The latter is essential for API manufacturing, where trace impurities can significantly impact downstream yields and regulatory compliance. Our standard offering is a pharmaceutical-grade 1-Propanone, 3-chloro-1-(4-octylphenyl)- with a minimum purity of 98.5% by GC, ensuring it meets the stringent requirements of GMP intermediate production. For research and pilot-scale work, we also supply a high-purity technical grade that balances cost and performance. The following table summarizes the typical specifications available for bulk orders.
| Parameter | Pharmaceutical Grade | Technical Grade |
|---|---|---|
| Purity (GC) | ≥98.5% | ≥95.0% |
| Appearance | White to off-white crystalline solid | Off-white to pale yellow solid |
| Melting Point | 42–45°C | 40–45°C |
| Moisture (KF) | ≤0.5% | ≤1.0% |
| Single Impurity | ≤0.5% | ≤2.0% |
| Residual Solvents | Complies with ICH Q3C | Reported on COA |
Selecting the appropriate grade is a critical cost-control measure. For large-scale campaigns, we often work with procurement teams to define a fit-for-purpose specification that avoids over-engineering while safeguarding the synthesis. This is where our experience as a global manufacturer of this Octylphenyl Propanone derivative becomes a tangible asset.
Certificate of Analysis (COA) Parameters and Batch Consistency
A robust COA is the cornerstone of quality assurance in B2B chemical sourcing. For 3-Chloro-1-(4-octylphenyl)propan-1-one, the COA must go beyond a simple purity number. We document appearance, melting point, water content, residual solvents by GC-HS, and a detailed impurity profile by HPLC or GC. Batch-to-batch consistency is non-negotiable, especially when the material is used in validated processes. Our production team monitors the manufacturing process closely to control the levels of the 2-chloro isomer and the corresponding alcohol, which are the most common by-products. In our experience, a subtle shift in the melting point range—even by 1–2°C—can indicate a change in the crystalline form that may affect dissolution kinetics in the next reaction step. Therefore, we report the melting point as a range observed on a calibrated apparatus, not a single value. Buyers should always request a representative COA before committing to a bulk purchase.

Bulk Packaging, Storage, and Handling for Industrial Supply Chains
Industrial logistics for 3-Chloro-1-(4-octylphenyl)propan-1-one must account for its physical state at ambient temperatures. With a melting point in the low 40s°C, the material is a solid at room temperature but can soften or partially melt during summer shipping or in warm warehouses. Standard packaging includes 25 kg fiber drums with an inner PE liner, or 50 kg HDPE pails. For larger volumes, we offer 210L steel drums with a removable lid, net weight 150–200 kg depending on density. The product is not classified as dangerous goods for transport under standard regulations, but it should be stored in a cool, dry place below 25°C to maintain free-flowing crystalline form. Prolonged exposure to temperatures above 35°C can lead to caking, which, while not affecting chemical purity, complicates material handling and sampling. We advise customers in tropical climates to consider refrigerated containers for sea freight during summer months. Our logistics team can arrange temperature-controlled shipping upon request. For specific guidance on winter shipping challenges, see our dedicated article on handling crystallization during cold-chain transport.
Non-Standard Parameters and Field Experience in Large-Scale Sourcing
Beyond the standard COA parameters, field experience reveals several non-standard behaviors that procurement managers should anticipate. One notable observation is the viscosity shift at sub-zero temperatures. While the pure compound is a crystalline solid, technical-grade material containing a few percent of oily impurities can exhibit a slush-like consistency when stored in unheated warehouses during winter. This does not indicate degradation but can make drum discharging difficult. Pre-warming the drum to 30–35°C for 24 hours restores a homogenous liquid state for easy transfer. Another edge case involves trace impurities affecting color. We have seen batches where a barely detectable level of an oxidation by-product (below 0.1%) imparts a faint yellow tint to the molten material. This has no impact on reactivity in the subsequent Friedel-Crafts acylation or reduction steps, but it can raise unfounded quality concerns. Our quality team addresses this by including a color specification (APHA ≤100 for molten product) in the COA for pharmaceutical-grade material. Finally, crystallization handling during large-scale reactions is a practical consideration. When this intermediate is used as a melt, it is crucial to ensure complete melting and homogenization before charging to avoid localized concentration gradients. These insights come from years of supporting kilo-lab to multi-ton campaigns and are part of the technical support we provide to our clients.
Supply Chain Reliability and Drop-in Replacement Strategy
For procurement managers, supply chain resilience is as critical as product quality. Our 3-Chloro-1-(4-octylphenyl)propan-1-one is manufactured in a dedicated, ISO-certified facility in Ningbo, China, with a production capacity exceeding 50 metric tons per year. This scale allows us to maintain safety stock and offer competitive bulk price structures. We position our product as a seamless drop-in replacement for existing qualified sources. The key to a successful drop-in is identical technical parameters: same CAS, same molecular structure, and a purity profile that matches or exceeds the incumbent supplier. We encourage customers to perform a parallel qualification by requesting a 1 kg sample and running a small-scale trial batch. Our technical team can provide a detailed impurity fate and purge study to support the regulatory filing. By choosing our pharmaceutical grade material, buyers gain a cost-efficient alternative without compromising on quality or supply security. Our dual sourcing of key raw materials and multi-train production setup further mitigate the risk of single-point failures. This quality assurance framework, combined with transparent communication, has made us a trusted partner for generic API manufacturers worldwide.

Frequently Asked Questions
What is the typical minimum order quantity (MOQ) for bulk purchases?
Our standard MOQ is 1 kg for sample qualification and 25 kg for commercial orders. For annual contracts, we can accommodate flexible delivery schedules with smaller lot sizes upon agreement.
Do you provide custom synthesis or different salt forms?
We focus on the base ketone form. However, we can discuss custom synthesis of related derivatives or specific impurity standards under a confidentiality agreement. Please inquire with your detailed requirements.
What is the standard lead time for a 100 kg order?
For spot inventory, dispatch is within 5 working days after order confirmation. For production against an order, the lead time is typically 4–6 weeks, depending on the campaign schedule.
How do you ensure batch-to-batch consistency for validated processes?
We employ a strict change control system. Any modification to raw material sources, process parameters, or equipment is evaluated for its impact on the quality profile. A bridging study can be provided to support customer regulatory filings.
Is the product available in solution form for direct use?
We supply the neat solid only. Preparing solutions in solvents like DMSO or dichloromethane is the responsibility of the end-user, as stability and concentration requirements vary by application.
