Description
Fmoc-L-isoleucine, PEPTIPURE® is an N-Fmoc-protected L-isoleucine building block for biochemistry, offered at a minimum purity of 98 %. Identified by CAS number 71989-23-6, it has the empirical formula C₂₁H₂₃NO₄ and a molar mass of 353,41 g/mol. This PEPTIPURE® grade material supports peptide synthesis and related biochemical workflows that rely on standard Fmoc protection chemistry. The combination of stated purity, clear molecular identity and convenient pack size helps method development, intermediate preparation and small synthesis campaigns in academic and industrial settings. Researchers can incorporate this protected amino acid into established Fmoc protocols for chain assembly, side-chain handling and subsequent deprotection sequences. Its specification profile makes it a practical choice whenever reproducible Fmoc-L-isoleucine quality is needed for peptide and biochemistry applications.

Questions about Fmoc-L-isoleucine, PEPTIPURE®, min. 98 %, for biochemistry, 10 g, glass
What is this article?
Fmoc-L-isoleucine, PEPTIPURE®, min. 98 %, 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.
