For any B2B procurement in the chemical industry, quality assurance is not just a buzzword; it's the cornerstone of successful operations. When sourcing 1-Chlorooctadecane (CAS 3386-33-2), understanding the key quality parameters and how to verify them is essential for R&D scientists, formulators, and procurement managers alike. This article outlines what buyers should look for to ensure they are obtaining high-quality 1-Chlorooctadecane from reputable China manufacturers.

Key Quality Indicators for 1-Chlorooctadecane

When you inquire about '1-chlorooctadecane price' or 'buy 1-chlorooctadecane,' the first thing to scrutinize is the product's quality. The primary indicators include:

  • Purity: This is arguably the most critical parameter. High-purity 1-Chlorooctadecane, typically specified as ≥99% (often determined by Gas Chromatography or GC), is vital for applications in organic synthesis, where even minor impurities can lead to unwanted side reactions, reduced yields, or contaminated final products. For analytical standards, purity requirements can be even higher.
  • Appearance: As described in product specifications, 1-Chlorooctadecane should be a clear, colorless to slightly yellowish liquid. Any significant deviation in color or clarity might indicate the presence of impurities or degradation.
  • Moisture Content: While not always explicitly stated for liquids, for many chemical intermediates, controlling moisture is important. Suppliers should have adequate packaging and handling procedures to maintain low moisture levels.
  • Identification: Confirming the identity of the chemical is crucial. CAS Number (3386-33-2) and synonyms like Octadecyl chloride should match your requirements. Analytical techniques like NMR (Nuclear Magnetic Resonance) and IR (Infrared Spectroscopy) are often used for structural confirmation, though these might be detailed in a full Certificate of Analysis (CoA).

The Role of the Certificate of Analysis (CoA)

A reliable manufacturer will always provide a detailed CoA with each batch of 1-Chlorooctadecane. This document should clearly list:

  • Product Name and CAS Number
  • Batch/Lot Number
  • Date of Manufacture and Expiry Date
  • Assay (Purity) with the method used (e.g., GC)
  • Physical properties such as appearance, density, and refractive index
  • Impurity profiles, if available
  • Storage recommendations

When engaging with a supplier for '1-chlorooctadecane manufacturer' in China, always request a sample CoA before placing a bulk order.

Choosing a Reliable Manufacturer

Beyond the product specifications, the reliability of the supplier is paramount. Consider these factors:

  • Experience and Reputation: Look for manufacturers with a proven history in producing fine chemicals.
  • Production Capacity: Can they consistently supply the quantities you need?
  • Customer Service: Responsiveness to inquiries and efficient handling of orders are key indicators.
  • Transparency: A supplier willing to discuss their quality control processes instills confidence.
