6-Chloroimidazo[1,2-a]pyridine-3-carboxylic Acid CAS 138642-97-4

Description

6-Chloroimidazo[1,2-a]pyridine-3-carboxylic Acid (C8H5ClN2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).

6-Chloroimidazo[1,2-a]pyridine-3-carboxylic Acid (CAS 138642-97-4), molecular formula C8H5ClN2O2 and molecular weight 196.59 g/mol, is a CATO reference standard with documented purity and traceability.

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-Chloroimidazo[1,2-a]pyridine-3-carboxylic Acid 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.
