2-(Chloromethyl)-3-(2-chlorophenyl)quinazolin-4(3H)-one CAS 22312-83-0

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(Chloromethyl)-3-(2-chlorophenyl)quinazolin-4(3H)-one.

2-(Chloromethyl)-3-(2-chlorophenyl)quinazolin-4(3H)-one (CAS 22312-83-0) is a high-purity analytical reference standard with the molecular formula C15H10Cl2N2O and a molecular weight of 305.16 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 2-(Chloromethyl)-3-(2-chlorophenyl)quinazolin-4(3H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 305.16 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), 2-(Chloromethyl)-3-(2-chlorophenyl)quinazolin-4(3H)-one 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.
