Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
tert-butyl N-(4-bromo-2-nitro-phenyl)-N-tert-butoxycarbonyl-carbamate (CAS 1228392-59-3), molecular formula C16H27BrN2O6 and molecular weight 423.30 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of tert-butyl N-(4-bromo-2-nitro-phenyl)-N-tert-butoxycarbonyl-carbamate (C16H27BrN2O6) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
