9-Fluorenylmethyl carbazate（Cat No.:L041436）is a protected hydrazine derivative commonly used in peptide and organic synthesis. It features a 9-fluorenylmethyl (Fm) group attached to a carbazate moiety, which stabilizes the molecule and allows for selective deprotection under mild basic conditions. This compound serves as a precursor for Fmoc-protected hydrazine reagents and is valuable for introducing hydrazide functionalities in solid-phase peptide synthesis and linker design. Its structural rigidity and ease of handling make it ideal for controlled release applications, drug conjugates, and preparing functionalized biomolecules with high chemoselectivity and purity.
