Description
L-Valine tert-butyl ester hydrochloride is a protected amino-acid building block supplied at min. 95 % purity for peptide and organic synthesis. Identified by CAS number 13518-40-6, it has the empirical formula C₉H₁₉NO₂·HCl and a molar mass of 209,71 g/mol. The tert-butyl ester masks the carboxyl function of L-valine while the hydrochloride salt improves handling and storage stability relative to the free base. This combination is widely applied in Boc- and related protection schemes, fragment condensation and the preparation of hydrophobic peptide segments. Clear molar-mass and CAS data facilitate stoichiometry calculations and regulatory documentation. The min. 95 % specification provides a practical purity level for routine synthetic work where reproducible incorporation of the L-valine residue is essential.

Questions about L-Valine tert-butyl ester hydrochloride, min. 95 %, 25 g
What is this article?
L-Valine tert-butyl ester hydrochloride, min. 95 %, 25 g 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.
