Pharmaceutical Intermediate
Fmoc-Asn(Trt)-OH is a protected asparagine derivative used as a building block in solid-phase peptide synthesis with the Fmoc strategy. It features a trityl (Trt) protecting group on the side-chain amide and a fluorenylmethoxycarbonyl (Fmoc) group on the alpha-amine, enabling selective deprotection during peptide assembly.
