The occurrence of 7-chloro-2-fluoro-[1,2,4]triazolo[1,5-a]pyridine is closely related to a nitrile group, fluorine/chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 7-chloro-2-fluoro-[1,2,4]triazolo[1,5-a]pyridine (CAS 2383844-89-9), a certified reference material (molecular formula C6H3ClFN3, MW 171.56 g/mol) for analytical method development and quality control.
Owing to a nitrile group, fluorine/chlorine substitution, an aromatic ring system, 7-chloro-2-fluoro-[1,2,4]triazolo[1,5-a]pyridine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 171.56 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), 7-chloro-2-fluoro-[1,2,4]triazolo[1,5-a]pyridine 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.
