Chemical Structure
Description
3-[1-(4-tert-Butylbenzoyl)piperidin-4-yl]-4-(4-methylphenyl)-4,5-dihydro-1H-1,2,4-triazol-5-one (C25H30N4O2) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
3-[1-(4-tert-Butylbenzoyl)piperidin-4-yl]-4-(4-methylphenyl)-4,5-dihydro-1H-1,2,4-triazol-5-one (CAS 1775547-32-4), molecular formula C25H30N4O2 and molecular weight 418.53 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.
