Used as an intermediate in organic synthesis, particularly in peptide chemistry and pharmaceutical manufacturing. It serves as a protected glycine derivative, where the allyloxycarbonyl (Alloc) group acts as a protecting group for the amino function. This allows selective deprotection under mild conditions using palladium catalysts, making it valuable in multi-step syntheses of complex molecules like drugs and bioactive peptides. Its stability under a range of reaction conditions and orthogonal protection capability enhance its utility in solid-phase and solution-phase synthesis.
