Description
L-Valine is a branched-chain amino acid offered at min. 99 % purity in CELLPURE® quality for cell-culture and life-science applications. Identified by CAS number 72-18-4 and EG nr. 200-773-6, it has the empirical formula C₅H₁₁NO₂, a molar mass of 117,15 g/mol and a density of 1,23 g/cm³. provides a practical laboratory quantity for media preparation, metabolic assays and protein chemistry. Sourced from manufacturer Carl ROTH, this CELLPURE® grade supports consistent supplementation of culture systems and controlled experimental setups. L-Valine is widely used where a defined essential amino acid is needed for nutrient formulations, reference work or specialised biochemical protocols. Reliable purity and clear physicochemical data facilitate reproducible results in cell-culture and research environments.

Questions about L-Valine, min. 99 %, CELLPURE®, 25 g, plastic
What is this article?
L-Valine, min. 99 %, CELLPURE®, 25 g, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Amino acids & peptides, inside Organic chemicals & synthesis reagents, in Lab chemicals.
An amino acid or a peptide is specified by the sequence or the residue, the chirality, and for a peptide the purity and the salt form. L and D forms are different compounds. A trifluoroacetate salt and a hydrochloride salt weigh differently per mole of peptide.
An organic chemical is built on carbon. In this category it is a building block or a reagent for making another molecule: a starting material, a coupling agent, a polymer, a PEG. Purity is a specification of which impurities remain. The structure, the CAS number and the grade decide whether two bottles are the same substance. Structures and properties are on PubChem. Nomenclature is IUPAC. Classification follows ECHA and the CLP Regulation.
