Chemical Structure
Description
As a certified reference material (CRM), 2,3-Bis(bromomethyl)quinoxaline 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.
2,3-Bis(bromomethyl)quinoxaline (CAS 3138-86-1), molecular formula C10H8Br2N2 and molecular weight 315.99 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution, 2,3-Bis(bromomethyl)quinoxaline is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 315.99 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.
