2-Phenylethyl Mercaptan Industrial Purity Coa: Technical Specifications and Bulk Supply
- [Molecular Integrity]: Optimized thiolation processes ensuring >98% GC purity with minimal disulfide formation.
- [Supply Chain]: Secure tonnage quantities available with verified factory-direct logistics and stability.
- [Documentation]: Full compliance with international safety standards including batch-specific COA and SDS.
In the realm of fine chemical manufacturing, securing a reliable source of sulfur-containing intermediates is critical for downstream application success. 2-Phenylethyl Mercaptan (CAS: 4410-99-5), also known commercially as Phenethyl thiol, serves as a vital building block in the fragrance, flavor, and pharmaceutical sectors. Procuring this compound requires more than just a vendor; it demands a partner capable of delivering consistent industrial purity and comprehensive technical documentation.
As a premier global manufacturer, NINGBO INNO PHARMCHEM CO.,LTD. specializes in the scale-up and production of high-value thiol intermediates. This guide details the technical parameters, quality assurance protocols, and supply chain advantages necessary for making informed procurement decisions regarding 2-phenyl-1-ethanethiol.
Industrial Purity Standards and Synthesis Overview
For process chemists and R&D teams, the primary concern regarding Phenethyl mercaptan is the impurity profile, specifically the presence of oxidation byproducts such as disulfides. Achieving high industrial purity requires a controlled synthesis route that minimizes exposure to oxidizing agents during the reaction and workup phases.
The standard organic synthesis for this molecule often involves the nucleophilic substitution of corresponding halides with thiourea or hydrosulfide salts, followed by hydrolysis. However, commercial-grade production must optimize this synthesis route to ensure high reaction yields and manageable exotherms. At NINGBO INNO PHARMCHEM CO.,LTD., our manufacturing process employs inert atmosphere techniques to prevent premature oxidation, ensuring the final liquid maintains its characteristic sulfurous, floral aroma without significant degradation.
Key technical considerations for quality control include:
- Gas Chromatography (GC): Primary method for assessing purity, typically targeting >97.0% to >99.0% depending on the grade.
- Water Content: Karl Fischer titration is essential to prevent hydrolysis or instability during storage.
- Heavy Metals: Critical for pharmaceutical intermediates to meet ICH Q3D guidelines.
Certificate of Analysis (COA) Details and Specifications
A robust Certificate of Analysis (COA) is the cornerstone of quality verification for any chemical supplier. When evaluating potential sources for 2-Phenylethyl Mercaptan, procurement officers should verify that the COA includes batch-specific data rather than generic specifications. The following table outlines the typical technical specifications expected for commercial-grade 2-phenyl-1-ethanethiol.
| Parameter | Specification Standard | Typical Result | Test Method |
|---|---|---|---|
| Appearance | Colorless to Pale Yellow Liquid | Colorless Liquid | Visual |
| Purity (GC) | ≥ 98.0% | 98.5% - 99.2% | GC Area % |
| Boiling Point | 217 - 218 °C | 217.5 °C | Distillation |
| Flash Point | ≥ 90 °C | 90 °C | Penky-Martens |
| Water Content | ≤ 0.5% | 0.1% | Karl Fischer |
| Identity (IR) | Conforms to Reference Standard | Conforms | FT-IR |
Verification of these parameters ensures batch-to-batch consistency, which is vital for maintaining the integrity of final fragrance formulations or pharmaceutical syntheses. Deviations in boiling point or purity can indicate the presence of isomers or unreacted starting materials that may compromise downstream reactions.
Procurement Strategy and Bulk Supply Stability
For executives and procurement managers, supply chain resilience is as important as chemical specifications. Market volatility can impact the bulk price and availability of sulfur-based intermediates. Partnering with an established manufacturer mitigates the risk of production stoppages and ensures steady access to tonnage quantities.
When sourcing high-purity 2-Phenylethanethiol, buyers should prioritize suppliers who offer factory-direct advantages. This eliminates intermediary markups and provides greater transparency regarding production schedules and inventory levels. Furthermore, a reliable chemical supplier will maintain safety stock to accommodate urgent requests without compromising quality.
Logistical considerations for this product include:
- Packaging: Typically supplied in nitrogen-purged drums (200kg) or isotanks to prevent oxidation during transit.
- Regulatory Compliance: Ensure the supplier provides REACH, TSCA, or other relevant regional compliance documentation.
- Lead Times: Verified manufacturers can offer predictable lead times for custom synthesis or standard stock items.
