Mesyloxybenzotriazole, CAS 54769-22-1, is the benzotriazole sulfonate ester C7H7N3O3S with molecular weight 213.21 g/mol. It is a reactive leaving-group precursor and synthetic intermediate rather than a classical degradation impurity, but it may persist as a process-related impurity when benzotriazole is activated by methanesulfonyl chemistry. The mesylate functionality can confer electrophilic character and warrants evaluation under impurity control strategies because such activated heteroaryl esters may participate in downstream alkylation chemistry. Trace determination typically relies on LC-MS/MS, LC-HRMS, or ion-pair HPLC with UV detection, supported by NMR for structural confirmation.Request a Quote
