1,7-Bis(tert-butoxycarbonylmethyl)-1,4,7,10-tetraazacyclododecane (CAS 162148-48-3), molecular formula C20H40N4O4 and molecular weight 400.56 g/mol, is a CATO reference standard with documented purity and traceability.
1,7-Bis(tert-butoxycarbonylmethyl)-1,4,7,10-tetraazacyclododecane (C20H40N4O4) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 1,7-Bis(tert-butoxycarbonylmethyl)-1,4,7,10-tetraazacyclododecane 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.
