Tetraethylene glycol monotosylate

Catalog No.: A42801
ADC Linker
Tetraethylene glycol monotosylate is a versatile cleavable linker primarily utilized in the synthesis of antibody-drug conjugates (ADCs). Its acylhydrazone moiety facilitates targeted drug delivery while enabling controlled release of cytotoxic agents. In addition to ADC applications, this compound can also serve as a linker in the development of proteolysis-targeting chimera (PROTAC) molecules, enhancing the specificity and efficacy of targeted protein degradation studies.
