Chemical Structure
Description
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 7-tert-Butoxycarbonyl-2-oxa-7-azaspiro[3.4]octane-5-carboxylic acid potassium salt is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 295.38 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
7-tert-Butoxycarbonyl-2-oxa-7-azaspiro[3.4]octane-5-carboxylic acid potassium salt (CAS 1823778-98-8), molecular formula C12H18NO5K and molecular weight 295.38 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
