For manufacturers across the pharmaceutical, nutritional, and fine chemical industries, understanding the precise specifications of raw materials like DL-Serine (CAS 302-84-1) is fundamental to product quality and consistency. As a prominent manufacturer and supplier, NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to providing DL-Serine that meets rigorous industry standards.

DL-Serine is a chiral amino acid with the chemical formula C3H7NO3. Its designation as 'DL' indicates it is a racemic mixture, containing equal parts of the D- and L-enantiomers. This racemic form offers unique advantages in certain synthetic pathways and applications. Typically, DL-Serine presents as a white crystalline powder, a physical characteristic that is straightforward to verify. However, the true value for manufacturers lies in its chemical purity and the absence of detrimental impurities.

A critical specification for manufacturers is the assay of DL-Serine, which indicates the percentage of the desired compound present. Our DL-Serine typically offers an assay ranging from 98.5% to 101.5%. This broad yet tight range ensures high purity and reliability for your downstream processes. Alongside the assay, manufacturers must be vigilant about impurity profiles. Key impurities to monitor include chloride (with a limit of not more than 500 ppm) and sulfate (NMT 300 ppm). Heavy metals, particularly lead (Pb), are also strictly controlled, with a maximum limit of 15 ppm. These specifications are vital for compliance with pharmaceutical and food-grade standards.

Other important physical and chemical properties that manufacturers should consider include loss on drying (NMT 0.2%), which indicates the amount of volatile matter, and residue on ignition (NMT 0.1%), which measures inorganic impurities remaining after combustion. For applications involving cell culture or food products, microbiological testing is indispensable. Our DL-Serine adheres to stringent microbial limits, with total viable aerobic counts not exceeding 1000 CFU/g, and moulds and yeasts not exceeding 100 CFU/g, while ensuring Escherichia coli is not detectable.

When seeking to purchase DL-Serine, manufacturers are advised to partner with suppliers who can provide comprehensive documentation and ensure a stable supply chain. As a manufacturer in China, NINGBO INNO PHARMCHEM CO.,LTD. offers competitive DL-Serine price points and reliable delivery for bulk orders. We are committed to being a trusted supplier, providing the high-quality DL-Serine essential for your manufacturing success.
