Chemical Structure

6,8-Dibromo-2-(chloromethyl)-3,4-dihydroquinazolin-4-one CAS 108635-30-9 chemical structure

Description

As a certified reference material (CRM), 6,8-Dibromo-2-(chloromethyl)-3,4-dihydroquinazolin-4-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.

6,8-Dibromo-2-(chloromethyl)-3,4-dihydroquinazolin-4-one (CAS 108635-30-9) is a high-purity analytical reference standard with the molecular formula C9H5Br2ClN2O and a molecular weight of 352.41 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, 6,8-Dibromo-2-(chloromethyl)-3,4-dihydroquinazolin-4-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 352.41 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
