Chemical Structure
Description
(6-Chloro-[1,2,4]triazolo[4,3-b]pyridazin-3-yl)methanamine hydrochloride (CAS 518050-85-6) is a high-purity analytical reference standard with the molecular formula C6H6ClN5HCl and a molecular weight of 220.06 g/mol.
The molecular framework of (6-Chloro-[1,2,4]triazolo[4,3-b]pyridazin-3-yl)methanamine hydrochloride (C6H6ClN5HCl) is characterized by a nitrile group, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), (6-Chloro-[1,2,4]triazolo[4,3-b]pyridazin-3-yl)methanamine hydrochloride 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.
