Chemical Structure
Description
As a certified reference material (CRM), 3-Bromo-2-methylbenzyl Alcohol 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 3-Bromo-2-methylbenzyl Alcohol (CAS 83647-43-2), a certified reference material (molecular formula C8H9BrO, MW 201.06 g/mol) for analytical method development and quality control.
Owing to a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system, 3-Bromo-2-methylbenzyl Alcohol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 201.06 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.
