Chemical Structure
Description
Dicyclohexylamine (S)-4-(((benzyloxy)carbonyl)amino)-5-(tert-butoxy)-5-oxopentanoate (CAS 34897-61-5), molecular formula C17H23NO6C12H23N and molecular weight 518.69 g/mol, is a CATO reference standard with documented purity and traceability.
Dicyclohexylamine (S)-4-(((benzyloxy)carbonyl)amino)-5-(tert-butoxy)-5-oxopentanoate (C17H23NO6C12H23N) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
