Chemical Structure
Description
3-(Bromomethyl)-5-methylisoxazole (CAS 130628-75-0), molecular formula C5H6BrNO and molecular weight 176.01 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amide group, a hydroxyl group, an ether linkage, bromine substitution, 3-(Bromomethyl)-5-methylisoxazole is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 176.01 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.
As a certified reference material (CRM), 3-(Bromomethyl)-5-methylisoxazole 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.
