Description
D-Leucine benzyl ester 4-toluenesulfonate is the D-configured leucine benzyl ester supplied as the 4-toluenesulfonate salt, identified by CAS number 17664-93-6 and empirical formula C₁₃H₁₉NO₂·C₇H₈O₃S. The molar mass is 393,5 g/mol. The benzyl ester enables established deprotection routes, and the tosylate salt form supports convenient weighing and storage in the laboratory. Offered by manufacturer Carl ROTH, the reagent belongs to the biochemicals range used for building enantiomerically defined intermediates. Research groups working on D-amino-acid incorporation, chiral probe design, or comparative L/D peptide sequences can employ this ester salt as a defined starting material. It is intended for synthetic and analytical workflows in academic and industrial laboratories that need reliable D-leucine derivatives for method development and preparative organic chemistry.

Questions about D-Leucine benzyl ester 4-toluenesulfonat, e salt, 10 g
What is this article?
D-Leucine benzyl ester 4-toluenesulfonat, e salt, 10 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.
