Description
As a certified reference material (CRM), 2-Chloro-1,3-bis(bromomethyl)benzene 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.
CATO supplies 2-Chloro-1,3-bis(bromomethyl)benzene (CAS 25006-87-5), a certified reference material (molecular formula C8H7Br2Cl, MW 298.40 g/mol) for analytical method development and quality control.
Owing to chlorine/bromine substitution, an aromatic ring system, 2-Chloro-1,3-bis(bromomethyl)benzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 298.40 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
