Certificado ISO 9001:2015 e ISO 14001:2015 · Suministro a laboratorios e industria desde el año 2000 · Certificado de Análisis (CoA) con cada lote
Fmoc-L-Arg(Pbf) is a protected amino acid derivative widely used in peptide synthesis, particularly for incorporating arginine residues with enhanced stability. It features an Fmoc (9-fluorenylmethyloxycarbonyl) protecting group on the alpha-amino function and a Pbf (2,2,4,6,7-pentamethyldihydrobenzofuran-5-sulfonyl) group on the guanidino side chain to prevent premature deprotection. This chemical has a CAS number of 154445-77-9, a molecular formula of C34H40N4O7S, and a molecular weight of 648.78 g/mol. It must be stored at -15 to -20°C and carries a **Warning** signal word for safety. Molekula supplies Fmoc-L-Arg(Pbf) from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
