L-Valine is an essential branched-chain amino acid critical for protein synthesis, muscle metabolism, and energy production in humans and animals. It’s widely used in pharmaceuticals, sports nutrition, and as a nutrient in cell culture media. This white crystalline powder has a CAS number of 72-18-4, molecular formula (CH3)2CHCH(NH2)CO2H, and a molecular weight of 117.15 g/mol. It requires no special storage—ambient conditions suffice—and carries no signal word for hazard classification.
Molekula supplies L-Valine at 98.5 - 101.5% purity in 100 g and 500 g packs, from £35.40 inc. VAT. It is in stock for same-day dispatch. Every batch ships with a certificate of analysis, and safety data sheets are available in 6 languages. Larger quantities, up to multi-tonne, are quoted on request.
