Description

Compared with other compounds in its class, the molecular weight of 225.28 g/mol gives tert-Butyl 7-oxo-5-azaspiro[3.4]octane-5-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

tert-Butyl 7-oxo-5-azaspiro[3.4]octane-5-carboxylate (CAS 2168075-35-0), molecular formula C12H19NO3 and molecular weight 225.28 g/mol, is a CATO reference standard with documented purity and traceability.

tert-Butyl 7-oxo-5-azaspiro[3.4]octane-5-carboxylate (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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), tert-Butyl 7-oxo-5-azaspiro[3.4]octane-5-carboxylate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
