Chloral Hydrate: Industrial Purity, COA & Bulk Supply
Chloral Hydrate Technical Specifications and Purity Grades for Industrial Applications
Chloral hydrate (2,2,2-trichloro-1,1-ethanediol) is a cornerstone intermediate in the synthesis of organophosphorus pesticides, particularly trichlorfon. At NINGBO INNO PHARMCHEM, we supply this compound with a focus on industrial purity and consistent quality. The standard industrial grade typically exceeds 99% purity, but for specialized applications, we offer higher grades. The synthesis route from trichloroacetaldehyde and water is well-established, yet achieving batch-to-batch uniformity requires rigorous process control. Our manufacturing process ensures minimal residual trichloroacetaldehyde, a critical factor for downstream reactions. For those seeking a reliable drop-in replacement for Sigma-Aldrich C8383 chloral hydrate, our product matches key specifications while offering significant cost advantages.
| Parameter | Industrial Grade | High Purity Grade |
|---|---|---|
| Assay (GC) | ≥99.0% | ≥99.5% |
| Melting Point | 51-55°C | 52-54°C |
| Water Content | ≤0.5% | ≤0.2% |
| Residual Trichloroacetaldehyde | ≤0.3% | ≤0.1% |
| Appearance | White crystalline solid | White crystalline solid |
These specifications are typical; please refer to the batch-specific COA for exact values. The high purity grade is particularly suited for sensitive syntheses where trace impurities could affect yield or color.
Critical COA Parameters and Batch-to-Batch Consistency in Chloral Hydrate Supply
For procurement managers, the Certificate of Analysis (COA) is the definitive document. Beyond assay, we monitor parameters that impact industrial performance. Water content is crucial because chloral hydrate is hygroscopic; excess moisture can skew stoichiometry and promote hydrolysis. Residual trichloroacetaldehyde, the starting material, must be tightly controlled to avoid side reactions. Our COA also includes appearance, melting range, and solubility. We understand that batch-to-batch consistency is non-negotiable for continuous processes. Our quality system ensures that each shipment of 2,2,2-trichloroethane-1,1-diol meets the agreed specifications, minimizing the need for process adjustments. For large-scale users, we can provide historical COA data to demonstrate long-term stability.
Bulk Packaging, Storage, and Handling of Chloral Hydrate: IBC and Drum Solutions
Chloral hydrate is typically shipped as a solid in 25 kg fiber drums or 500 kg supersacks. For liquid handling, we can supply molten chloral hydrate in 210L drums or IBC totes, provided the temperature is maintained above its melting point (around 55°C). This is particularly advantageous for continuous reactor feeds. Storage requires a cool, dry environment to prevent caking and degradation. The compound is stable under recommended conditions, but exposure to moisture or high temperatures can lead to hydrolysis, releasing trichloroacetaldehyde. Our logistics team ensures that packaging is robust and compliant with international transport regulations. We do not claim EU REACH compliance, but our packaging meets standard safety requirements for chemical shipments.
Non-Standard Field Observations: Viscosity and Crystallization Behavior of Chloral Hydrate
From field experience, one non-standard parameter that often surprises users is the viscosity behavior of molten chloral hydrate near its freezing point. As the temperature drops below 60°C, the viscosity increases sharply, and crystallization can occur rapidly if the material is not kept under agitation or trace water is present. This can lead to line blockages in unheated transfer systems. We advise customers to maintain molten chloral hydrate at 65-70°C with gentle recirculation. Another edge case is the occasional pinkish discoloration in older samples, which is typically due to trace iron contamination or slight decomposition. While this does not affect reactivity for most applications, it can be a concern for color-sensitive products. Our high-purity grade minimizes this risk through controlled synthesis and packaging under inert atmosphere.
Chloral Hydrate as a Drop-in Replacement: Cost and Supply Chain Advantages
For manufacturers currently sourcing chloral hydrate from major chemical suppliers, our product serves as a seamless drop-in replacement. We match the technical parameters of leading brands, including the widely referenced Sigma-Aldrich C8383, but at a more competitive bulk price. Our global manufacturing footprint and strategic inventory locations ensure reliable supply, even during market fluctuations. By switching to NINGBO INNO PHARMCHEM, you gain a partner that understands the nuances of industrial-scale synthesis.

We offer flexible MOQs and can accommodate tonnage orders with short lead times.
Frequently Asked Questions
What is the minimum order quantity (MOQ) for chloral hydrate?
Our standard MOQ is 100 kg for trial orders, but we can accommodate smaller quantities for initial evaluations. For regular supply, we typically ship in 500 kg supersacks or full pallets of 25 kg drums. Contact our sales team for tailored solutions.
What is the typical lead time for bulk orders?
Lead times vary by destination and order size. For stocked grades, we can dispatch within 2-3 weeks. Custom packaging or large tonnage may require 4-6 weeks. We maintain safety stock for key customers to ensure just-in-time delivery.
Can you provide a sample for qualification?
Yes, we offer free samples of our industrial and high-purity grades for technical evaluation. Please request a sample through our website, and we will ship it with a provisional COA.
How do you ensure batch-to-batch consistency?
We employ rigorous in-process controls and final QC testing per validated methods. Each batch is analyzed for assay, water content, residual aldehyde, and appearance. We retain samples for two years and can provide historical data upon request.
What are the payment terms?
We typically work with T/T in advance or irrevocable L/C at sight for new customers. For established relationships, we offer net 30 or net 60 terms. All transactions are in USD or EUR.
