Heterobifunctional PEGs with Protected Amine
Heterobifunctional PEG FMOC Amine and TBOC Amine from JenKem Technology are generally employed as crosslinking agents or as spacers between two different chemical entities. The 9-fluorenylmethoxycarbonyl (Fmoc) protective group can be removed by treatment with piperidine to release a free amine. Tert-butyloxycarbonyl (Boc) protection group can be removed by treatment with trifluoroacetic acid (TFA) or other common acids to provide a free amine. The PEG moiety in the heterobifunctional PEG derivatives provides water solubility, biocompatibility, and flexibility. Applications of heterobifunctional PEGs are generally geared towards the development of antibody drug conjugates (ADC’s).
