Product Description
DL-Valine, also known as DL-α-aminoisovaleric acid or DL-2-amino-3-methylbutyric acid, is a racemic amino acid with the molecular formula C₅H₁₁NO₂ and a molecular weight of approximately 117.15 g/mol.
It typically appears as a white crystalline powder. Its reported melting or decomposition temperature is around 295°C, although the exact value may vary depending on the test method and product specifications. As a solid amino acid, DL-Valine may decompose upon heating rather than exhibit a conventional boiling point at atmospheric pressure.
DL-Valine contains approximately equal proportions of its D- and L-enantiomers. Its specific rotation is therefore generally close to zero under suitable measurement conditions. The compound is hygroscopic and readily soluble in water. For accurate storage, handling, and quality-control information, refer to the supplier's current Technical Data Sheet (TDS) and Safety Data Sheet (SDS).
