tert-butyl cis-2-(p-tolylsulfonyloxy)-6-azaspiro[3.4]octane-6-carboxylate (CAS 1256240-97-7), molecular formula C19H33NO5S and molecular weight 387.53 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of tert-butyl cis-2-(p-tolylsulfonyloxy)-6-azaspiro[3.4]octane-6-carboxylate (C19H33NO5S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures tert-butyl cis-2-(p-tolylsulfonyloxy)-6-azaspiro[3.4]octane-6-carboxylate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
