Used in the synthesis of peptidoglycan fragments for immunological research, particularly in studies related to bacterial cell wall recognition and immune response activation. Serves as a key intermediate in constructing complex carbohydrate-peptide structures found in bacterial antigens. Enables investigation of host-pathogen interactions and supports development of vaccines and adjuvants by mimicking natural bacterial cell wall components. Its protected functional groups allow selective deprotection and coupling in multi-step organic syntheses targeting bioactive molecules.
