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.
(4-(5-Chloro-2-methylphenyl)piperazin-1-yl)(2-phenoxypyridin-3-yl)methanone (CAS 1024351-82-3), molecular formula C23H22ClN3O2 and molecular weight 407.89 g/mol, is a CATO reference standard with documented purity and traceability.
(4-(5-Chloro-2-methylphenyl)piperazin-1-yl)(2-phenoxypyridin-3-yl)methanone (C23H22ClN3O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine 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.
