Description
Fmoc-L-norleucine is an N-Fmoc-protected non-proteinogenic amino acid used as a building block in peptide synthesis and medicinal chemistry. It is registered under CAS number 77284-32-3, with the empirical formula C₂₁H₂₃NO₄ and a molar mass of 353,41 g/mol. The Fmoc group on the α-amino function enables orthogonal protection strategies typical of modern solid-phase and solution-phase peptide work. Norleucine provides a linear aliphatic side chain that can serve as a methionine or leucine surrogate in structure–activity studies, hydrophobic packing analyses, and analogue design. Material from manufacturer Carl ROTH supports laboratories that require a clearly identified Fmoc-amino acid with documented molecular formula and molar mass for protocol development, library synthesis, and biochemical research. Users can apply it in automated or manual peptide assembly, side-chain scanning, and the preparation of custom peptides where a defined L-norleucine residue is specified, while relying on the CAS number and compositional data for inventory control and experimental documentation.

Questions about Fmoc-L-norleucine, 25 g
What is this article?
Fmoc-L-norleucine, 25 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.
