Chemical Structure
Description
The occurrence of Sodium 8-chloro-[1,2,4]triazolo[4,3-a]pyridine-3-carboxylate is closely related to a salt form, an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Sodium 8-chloro-[1,2,4]triazolo[4,3-a]pyridine-3-carboxylate (CAS 2251053-22-0), molecular formula C7H3ClN3O2Na and molecular weight 219.56 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a salt form, an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, Sodium 8-chloro-[1,2,4]triazolo[4,3-a]pyridine-3-carboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 219.56 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), Sodium 8-chloro-[1,2,4]triazolo[4,3-a]pyridine-3-carboxylate 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.
