For any B2B procurement in the chemical and pharmaceutical sectors, quality assurance is non-negotiable. DL-Homocystine (CAS 462-10-2) is a critical intermediate, and understanding its key quality specifications is paramount for successful application. This guide is designed to assist procurement managers and R&D scientists in identifying high-quality DL-Homocystine when sourcing from suppliers, particularly those based in China.

The fundamental starting point for assessing DL-Homocystine quality is its CAS number: 462-10-2. This unique identifier ensures you are sourcing the correct chemical entity. Beyond the CAS number, the purity of the compound is perhaps the most critical specification. For pharmaceutical intermediates like DL-Homocystine, purity levels of 97% or higher are typically required to ensure efficacy and safety in downstream processes. Reputable DL-Homocystine manufacturers will provide a Certificate of Analysis (CoA) detailing the purity, often determined by techniques such as High-Performance Liquid Chromatography (HPLC).

Other important physical and chemical properties to verify include its appearance, typically described as a white to off-white solid. The molecular formula (C8H16N2O4S2) and molecular weight (268.35 g/mol) are fundamental identifiers. Melting point, usually around 281-284°C with decomposition, and density (approx. 1.444 g/cm³) are also key parameters that indicate product consistency and adherence to specifications. When you buy DL-Homocystine, ensure these properties are clearly stated by the supplier.

When sourcing from China, it is especially important to work with manufacturers that have robust quality control systems. This includes rigorous testing of raw materials, in-process monitoring, and final product analysis. Understanding the synthesis of DL-Homocystine can also provide insights into potential impurities. A trusted supplier will be transparent about their manufacturing processes and quality assurance protocols. Inquiring about compliance with relevant industry standards (e.g., GMP for pharmaceutical applications, if applicable) is also a prudent step.

The price of DL-Homocystine should always be considered in conjunction with these quality parameters. While competitive pricing is attractive, compromising on purity or consistency can lead to significant setbacks in research and development. Choosing a reliable DL-Homocystine supplier that balances quality with cost-effectiveness is key to a successful procurement strategy. We encourage all potential buyers to reach out to us for detailed specifications and samples to ensure our DL-Homocystine meets your exact quality requirements.
