Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
cis-1-Methyl-7-oxo-3-aza-bicyclo[3.2.0]heptane-3-carboxylic acid tert-butyl ester (CAS 1263378-91-1), molecular formula C12H19NO3 and molecular weight 225.28 g/mol, is a CATO reference standard with documented purity and traceability.
cis-1-Methyl-7-oxo-3-aza-bicyclo[3.2.0]heptane-3-carboxylic acid tert-butyl ester (C12H19NO3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, 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 cis-1-Methyl-7-oxo-3-aza-bicyclo[3.2.0]heptane-3-carboxylic acid tert-butyl ester 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.
