Description

CATO supplies 6-Benzyl 5-tert-butyl (6S)-4-oxo-5-azaspiro[2.4]heptane-5,6-dicarboxylate (CAS 1628205-95-7), a certified reference material (molecular formula C19H23NO5, MW 345.39 g/mol) for analytical method development and quality control.

Structurally, 6-Benzyl 5-tert-butyl (6S)-4-oxo-5-azaspiro[2.4]heptane-5,6-dicarboxylate (C19H23NO5) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 345.39 g/mol, it falls into the moderately-high-molecular-weight range. 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).

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.
