Chemical Structure
Description
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.
CATO supplies Tert-butyl 4-methyl-2-(2-oxo-2-phenylethyl)-2,8-diazaspiro[4.5]Decane-8-carboxylate (CAS 1899102-35-2), a certified reference material (molecular formula C22H32N2O3, MW 372.50 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Tert-butyl 4-methyl-2-(2-oxo-2-phenylethyl)-2,8-diazaspiro[4.5]Decane-8-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 372.50 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
