Description
D-Valine is a chiral amino acid offered at a minimum purity of 98,5 % for biochemistry. Identified by CAS number 640-68-6 and the empirical formula C₅H₁₁NO₂, this compound has a molar mass of 117,2 g/mol and a density of 0,45 g/cm³. As the D-enantiomer of valine, it serves as a valuable building block in peptide chemistry, stereoselective synthesis and studies of non-proteinogenic amino acids. Laboratories employ it in metabolic pathway research, enzyme substrate work and the preparation of specialised culture media. The product is Its biochemical grade supports applications that demand defined optical configuration and consistent purity, including analytical reference use and organic transformations. Careful handling under standard laboratory conditions helps maintain integrity during weighing and dissolution. This D-Valine grade is intended for research and development environments focused on amino-acid chemistry and related life-science investigations.

Questions about D-Valine, min. 98.5 %, for biochemistry, 5 g, plastic
What is this article?
D-Valine, min. 98.5 %, for biochemistry, 5 g, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Click chemistry, bioconjugation & synthesis reagents, inside Biochemicals & reagents, in Microbiology lab supplies.
Click and bioconjugation reagents join two molecules under mild conditions, often an azide to an alkyne, or an NHS ester to an amine. The linker length and the reactive group are the specification. They are small bottles of a reactive compound, and moisture often ruins them.
A biochemical is a molecule of life, sold as a reagent: an amino acid, a sugar, a nucleotide, a lipid, an enzyme, an antibiotic. The difference from a bulk chemical is that the use is a biological one, and the impurities that matter are the ones that change that use. An enzyme is specified by activity, not only by mass. An antibiotic is specified by potency. Papers are on PubMed. Structures are on PubChem. Strains and lines that consume these reagents are at ATCC.
