Description
Fmoc-L-leucine, PEPTIPURE® is an N-Fmoc-protected L-leucine derivative for biochemistry, supplied at a minimum purity of 95 %. It carries CAS number 35661-60-0, the empirical formula C₂₁H₂₃NO₄ and a molar mass of 353,41 g/mol. This PEPTIPURE® grade reagent is intended for peptide synthesis and other biochemical applications that use Fmoc-based protection strategies. The stated purity and molecular data help maintain consistency across solid-phase and solution-phase coupling workflows. Scientists can apply this building block within standard Fmoc chemistry sequences for chain elongation, intermediate isolation and downstream deprotection. The practical pack size suits method optimisation, small synthesis runs and routine biochemical work that depends on reliable Fmoc-L-leucine quality in research and development laboratories.

Questions about Fmoc-L-leucine, PEPTIPURE®, min. 95 %, for biochemistry, 10 g, glass
What is this article?
Fmoc-L-leucine, PEPTIPURE®, min. 95 %, 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 Life Science & Microbiology.
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.
