Chemical Structure
Description
Tert-butyl 4-(4-((4-chlorobenzamido)methyl)phenyl)piperazine-1-carboxylate (C23H28ClN3O3) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Tert-butyl 4-(4-((4-chlorobenzamido)methyl)phenyl)piperazine-1-carboxylate (CAS 866018-62-4), molecular formula C23H28ClN3O3 and molecular weight 429.94 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.
