Thalidomide-5-O-C2-NH2 hydrochloride(CAT: I040617) is a minimal-linker derivative of thalidomide featuring an ethylamine (C2) chain at the 5-hydroxy position, designed for precision conjugation in protein degradation and ligand development. The short linker length provides close spatial proximity between the thalidomide core and attached payload, enabling fine-tuned steric control in PROTAC construction and cereblon-binding studies. This compact architecture is ideal for exploring structure–activity relationships where linker length significantly influences activity and selectivity. Thalidomide-5-O-C2-NH2 hydrochloride is widely used in chemical biology and medicinal chemistry research focused on targeted therapeutics and E3 ligase-mediated protein ubiquitination systems.
