Chemical Structure
Description
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.
3-bromo-5-(bromomethyl)pyridine hydrobromide (CAS 173999-33-2), molecular formula C6H5Br2NHBr and molecular weight 331.83 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C6H5Br2NHBr, 3-bromo-5-(bromomethyl)pyridine hydrobromide contains a nitrile group, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 331.83 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
As a certified reference material (CRM), 3-bromo-5-(bromomethyl)pyridine 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.
