3-Ethyl-N-(3-fluorophenyl)-[1,2,4]triazolo-[4,3-a]pyridine-8-sulfonamide CAS 1291486-53-7 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 3-Ethyl-N-(3-fluorophenyl)-[1,2,4]triazolo-[4,3-a]pyridine-8-sulfonamide.

CATO supplies 3-Ethyl-N-(3-fluorophenyl)-[1,2,4]triazolo-[4,3-a]pyridine-8-sulfonamide (CAS 1291486-53-7), a certified reference material (molecular formula C14H13FN4O2S, MW 320.34 g/mol) for analytical method development and quality control.

Structurally, 3-Ethyl-N-(3-fluorophenyl)-[1,2,4]triazolo-[4,3-a]pyridine-8-sulfonamide (C14H13FN4O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 320.34 g/mol, it falls into the moderately-high-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), 3-Ethyl-N-(3-fluorophenyl)-[1,2,4]triazolo-[4,3-a]pyridine-8-sulfonamide 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.
