Description
Fmoc-O-benzylphospho-L-serine is a protected phosphoamino acid building block with CAS number 158171-14-3 and empirical formula C₂₅H₂₄NO₈P. It has a molar mass of 497,43 g/mol. The Fmoc group on the α-amino function and the benzyl-protected phosphate on the serine side chain enable controlled incorporation of phosphoserine motifs during solid-phase assembly, followed by selective deprotection to reveal the free phospho residue. Such intermediates are central to studies of protein phosphorylation, phosphopeptide epitopes and signalling-pathway mimics. Offered by manufacturer Carl ROTH, this derivative supports preparation of site-specifically phosphorylated peptides for biochemical assays, antibody work and mass-spectrometric standards. Defined molecular formula and a compact research pack suit Fmoc SPPS where precise stoichiometry and side-chain integrity matter. Laboratories engaged in post-translational modification chemistry, kinase-substrate investigations or phosphoproteomics can use this compound as a practical protected intermediate for introducing O-phosphoserine under standard Fmoc protocols.

Questions about Fmoc-O-benzylphospho-L-serine, 2 g
What is this article?
Fmoc-O-benzylphospho-L-serine, 2 g is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Amino acids & peptides, inside Organic chemicals & synthesis reagents, in Lab chemicals.
An amino acid or a peptide is specified by the sequence or the residue, the chirality, and for a peptide the purity and the salt form. L and D forms are different compounds. A trifluoroacetate salt and a hydrochloride salt weigh differently per mole of peptide.
An organic chemical is built on carbon. In this category it is a building block or a reagent for making another molecule: a starting material, a coupling agent, a polymer, a PEG. Purity is a specification of which impurities remain. The structure, the CAS number and the grade decide whether two bottles are the same substance. Structures and properties are on PubChem. Nomenclature is IUPAC. Classification follows ECHA and the CLP Regulation.
Which category should I open next?
The category is Organic chemicals & synthesis reagents. The sub-category is Amino acids & peptides. The catalogue is Lab chemicals.
