For businesses in the pharmaceutical and chemical industries, sourcing high-quality L-Serine methyl ester hydrochloride (CAS 5680-80-8) is paramount. As a critical pharmaceutical intermediate, its purity and adherence to stringent standards directly impact the efficacy and safety of downstream products. This article serves as a guide for procurement managers and R&D scientists looking to buy this essential compound, with a focus on understanding quality, certifications, and identifying reliable manufacturers and suppliers, particularly within China.

L-Serine methyl ester hydrochloride, often identified by its CAS number 5680-80-8, is a white powder characterized by its high assay, typically 99% or higher. Its molecular formula, C4H10ClNO3, hints at its utility as a building block in complex organic synthesis. For professionals in drug development and fine chemical manufacturing, the ability to procure this intermediate with consistent quality is non-negotiable. When considering a purchase, understanding the quality standards such as USP, BP, EP, and FCC is crucial, as these signify compliance with international benchmarks for pharmaceutical and food-grade ingredients.

Identifying a reputable manufacturer and supplier is the next critical step. China has emerged as a significant global hub for chemical production, offering competitive pricing without compromising on quality when selecting the right partners. Look for suppliers who provide comprehensive documentation, including Certificates of Analysis (COA), Safety Data Sheets (SDS), and evidence of certifications like GMP (Good Manufacturing Practice) and SGS. GMP certification, in particular, indicates that the manufacturing processes meet rigorous quality and safety standards, a vital consideration for pharmaceutical intermediates. For instance, a manufacturer stating 99.5% MIN assay and holding GMP/SGS certifications provides a strong assurance of product integrity.

When inquiring about pricing, be prepared to discuss minimum order quantities (MOQ) and desired packaging. Suppliers may offer different price points based on volume, and standard packaging options often include 25kg fiber drums. For those looking to establish a long-term supply chain, building a relationship with a manufacturer that offers online purchase support and readily available technical data can significantly streamline the procurement process. Requesting samples before a large purchase is also a standard practice to verify product quality firsthand.

In summary, to successfully buy L-Serine methyl ester hydrochloride (CAS 5680-80-8), prioritize suppliers who demonstrate a strong commitment to quality through high purity assays and international certifications. By partnering with reputable manufacturers and suppliers in China, you can secure a consistent and cost-effective supply of this vital pharmaceutical intermediate, empowering your research and production goals.
