Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies tert-Butyl 4-(4-bromophenyl)-4-(4-chlorophenyl)-piperidine-1-carboxylate (CAS 857532-23-1), a certified reference material (molecular formula C22H25BrClNO2, MW 450.80 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, tert-Butyl 4-(4-bromophenyl)-4-(4-chlorophenyl)-piperidine-1-carboxylate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 450.80 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
As a certified reference material (CRM), tert-Butyl 4-(4-bromophenyl)-4-(4-chlorophenyl)-piperidine-1-carboxylate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
