Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 8-Bromo-5-chloro-[1,2,4]triazolo[4,3-a]pyridine-6-carbonitrile, 97%.
8-Bromo-5-chloro-[1,2,4]triazolo[4,3-a]pyridine-6-carbonitrile, 97% (CAS 1823924-70-4), molecular formula C7H2BrClN4 and molecular weight 257.47 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 8-Bromo-5-chloro-[1,2,4]triazolo[4,3-a]pyridine-6-carbonitrile, 97% (C7H2BrClN4) contains a nitrile group, chlorine/bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 257.47 g/mol, it falls into the medium-molecular-weight range. 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), 8-Bromo-5-chloro-[1,2,4]triazolo[4,3-a]pyridine-6-carbonitrile, 97% 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.
