For professionals in the pharmaceutical and biotechnology industries, understanding the precise specifications of raw materials is fundamental to ensuring product safety, efficacy, and regulatory compliance. When sourcing L-Glutamine, paying close attention to its technical details is crucial. This guide aims to demystify these specifications, empowering buyers to make informed decisions when they seek to buy L-Glutamine.
The most fundamental identifier for L-Glutamine is its Chemical Abstracts Service (CAS) number: 56-85-9. This unique numerical identifier ensures that you are procuring the correct chemical entity, distinguishing it from isomers or related compounds. Beyond the CAS number, the 'Assay' is a critical parameter. For high-quality L-Glutamine suitable for pharmaceutical and cell culture applications, an assay of 99.0-101.0% is typically required. This indicates the high degree of purity and minimal presence of impurities.
Pharmacopoeia compliance is another non-negotiable aspect. Reputable suppliers, such as NINGBO INNO PHARMCHEM CO.,LTD., will clearly state that their L-Glutamine meets the standards set by major pharmacopoeias like the United States Pharmacopeia (USP), European Pharmacopoeia (EP), and Japanese Pharmacopoeia (JP). These standards encompass a range of tests, including limits for heavy metals, residue on ignition, loss on drying, and related substances, ensuring that the product is safe for its intended use.
When evaluating a manufacturer or supplier, look for detailed specifications regarding physical appearance (e.g., white crystalline powder), solubility, and optical rotation. For instance, the specific rotation of L-Glutamine at 20°C in water is typically within a defined range, which serves as an additional indicator of purity and identity. Furthermore, understanding the required storage conditions – usually controlled room temperature in a tight container – is vital for maintaining product integrity post-purchase.
At NINGBO INNO PHARMCHEM CO.,LTD., we are committed to transparency and providing comprehensive documentation for our L-Glutamine. As a leading supplier in China, we ensure that all technical data, including Certificates of Analysis (CoA), clearly outline these critical specifications. If you are looking to purchase pharmaceutical grade L-Glutamine or cell culture grade L-Glutamine, understanding these parameters will help you select the most suitable product and a reliable supplier.
