Chemical Structure
Description
2,4-Dihydroxyphenethylamine Hydrobromide (CAS 93073-96-2), molecular formula C8H11NO2HBr and molecular weight 234.09 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, 2,4-Dihydroxyphenethylamine Hydrobromide is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 234.09 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), 2,4-Dihydroxyphenethylamine Hydrobromide 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.
