Description
Fmoc-O-benzylphospho-L-tyrosine is an Fmoc-protected phosphotyrosine building block supplied for solid-phase and solution-phase peptide chemistry. Identified by CAS number 191348-16-0 and empirical formula C₃₁H₂₈NO₈P, it has a molar mass of 573,53 g/mol. The O-benzyl phospho ester masks the phosphate during chain assembly, enabling controlled incorporation of phosphotyrosine motifs into synthetic peptides used in signalling, kinase and phosphatase studies. Laboratories engaged in epitope mapping, phosphopeptide library construction and structure–activity work benefit from a clearly defined Fmoc amino acid derivative that integrates into standard Fmoc/tBu protocols. The material is positioned for biochemical and medicinal chemistry applications where reproducible incorporation of protected phospho-tyrosine residues is essential. Handle according to good laboratory practice for protected amino acids and related organophosphorus intermediates.

Questions about Fmoc-O-benzylphospho-L-tyrosine, 1 g
What is this article?
Fmoc-O-benzylphospho-L-tyrosine, 1 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.
