CATO supplies tert-butyl 4-(3-bromophenyl)-3-oxo-2,8-diazaspiro[4.5]decane-8-carboxylate (CAS 1375303-50-6), a certified reference material (molecular formula C19H25BrN2O3, MW 409.32 g/mol) for analytical method development and quality control.
tert-butyl 4-(3-bromophenyl)-3-oxo-2,8-diazaspiro[4.5]decane-8-carboxylate (C19H25BrN2O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
