Product Description
DL-Valine (CAS 516-06-3) is a racemic form of valine, an alpha-amino acid with the molecular formula C₅H₁₁NO₂ and a molecular weight of approximately 117.15 g/mol. Its structure includes an amino group, a carboxyl group, and a branched isopropyl side chain. Unlike L-valine or D-valine supplied as a single stereoisomer, DL-valine contains both enantiomeric forms.
This stereochemical distinction is important when selecting amino acid materials for research, analytical procedures, or chemical synthesis. The presence of both enantiomers can affect the outcome of experiments and processes that are sensitive to chirality, so the specified stereochemical composition should be checked before use.
DL-Valine is generally supplied as a white crystalline powder. Actual appearance, assay, moisture content, and impurity limits depend on the supplied grade and production specification. Buyers should confirm the intended application, required purity, particle characteristics if relevant, packaging, and storage conditions before placing an order. For pharmaceutical, food, or other regulated uses, verify that the particular grade is suitable under the applicable requirements.
