Description
As a certified reference material (CRM), 4-Hydrazinyl-2-methylpyridine 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.
4-Hydrazinyl-2-methylpyridine hydrobromide (CAS 1301739-49-0), molecular formula C6H9N3HBr and molecular weight 204.07 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C6H9N3HBr, 4-Hydrazinyl-2-methylpyridine hydrobromide contains a nitrile group, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 204.07 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
