Chemical Structure

N-(4-chlorobenzyl)-2,4-diphenylpyrimidine-5-carboxamide CAS 321433-27-6 chemical structure

Description

N-(4-chlorobenzyl)-2,4-diphenylpyrimidine-5-carboxamide (CAS 321433-27-6) is a high-purity analytical reference standard with the molecular formula C24H18ClN3O and a molecular weight of 399.87 g/mol.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, N-(4-chlorobenzyl)-2,4-diphenylpyrimidine-5-carboxamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 399.87 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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-chlorobenzyl)-2,4-diphenylpyrimidine-5-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.
