Description
DL-Leucine is a branched-chain amino acid reagent with a minimum purity of 98 % for biochemistry, identified by CAS number 328-39-2 and empirical formula C₆H₁₃NO₂. With a molar mass of 131,17 g/mol, it supports accurate preparation of solutions and stoichiometric calculations in laboratory practice. provides a practical quantity for culture media work, peptide-related studies, metabolic research, and routine biochemical applications that need a defined leucine source. Offered by manufacturer Carl ROTH, the material delivers consistent quality for method development, reference use, and preparative experiments. Researchers employ DL-leucine in organic and bioorganic synthesis as well as in analytical workflows where reproducible amino-acid input is essential. Clear documentation of purity, formula, and molar mass facilitates integration into standard laboratory protocols, while the pack format supports efficient handling and controlled consumption across multiple assays.

Questions about DL-Leucine, min. 98 %, for biochemistry, 25 g, plastic
What is this article?
DL-Leucine, min. 98 %, for biochemistry, 25 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.
