Description
L-Isoleucine is an essential branched-chain amino acid supplied at a minimum purity of 98.5 % in USP quality for biochemistry applications. With CAS number 73-32-5, EG number 200-798-2 and the empirical formula C₆H₁₃NO₂, it has a molar mass of 131,18 g/mol and a density of 1,207 g/cm³. This is suited to peptide synthesis, culture media formulation, metabolic studies and other laboratory workflows that require a defined L-isomer amino acid standard. The material supports quantitative work where consistent composition and documented identity matter. Offered from manufacturer Carl ROTH, the product fits routine biochemical research, method development and teaching laboratories that specify USP-grade isoleucine. Clear labelling of CAS, EG and physical data aids inventory control and protocol documentation. Use under standard laboratory conditions appropriate for amino acid reagents in glass packaging.

Questions about L-Isoleucine, min. 98.5 %, USP, for biochemistry, 10 g, glass
What is this article?
L-Isoleucine, min. 98.5 %, USP, for biochemistry, 10 g, glass 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.

What should I check before I order?
The technical information on this page is the manufacturer's sheet. Read that, not a rewritten specification.
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
