Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(4-bromophenyl)-4-[2-(2-chloroethyl)benzamido]piperidine-1-carboxamide.
N-(4-bromophenyl)-4-[2-(2-chloroethyl)benzamido]piperidine-1-carboxamide (CAS 2044796-86-1), molecular formula C21H23BrClN3O2 and molecular weight 464.78 g/mol, is a CATO reference standard with documented purity and traceability.
N-(4-bromophenyl)-4-[2-(2-chloroethyl)benzamido]piperidine-1-carboxamide (C21H23BrClN3O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), N-(4-bromophenyl)-4-[2-(2-chloroethyl)benzamido]piperidine-1-carboxamide 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.
