A strategy for the conjugation of alcohol‐containing payloads to antibodies has been developed and involves the methylene alkoxy carbamate (MAC) self‐immolative unit. A series of MAC β‐glucuronide model constructs were prepared to evaluate stability and enzymatic release, and the results demonstrated high stability at physiological pH in a substitution‐dependent manner. All the MAC model compounds
