4-Chloro-6-(dibromomethyl)quinazoline CAS 153436-67-0 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 4-Chloro-6-(dibromomethyl)quinazoline.

CATO supplies 4-Chloro-6-(dibromomethyl)quinazoline (CAS 153436-67-0), a certified reference material (molecular formula C9H5Br2ClN2, MW 336.41 g/mol) for analytical method development and quality control.

4-Chloro-6-(dibromomethyl)quinazoline (C9H5Br2ClN2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine/bromine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

CATO manufactures 4-Chloro-6-(dibromomethyl)quinazoline under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
