Description

Compared with other compounds in its class, the molecular weight of 231.04 g/mol gives 4,6-Dichloro-1H-pyrrolo[3,2-c]pyridine-2-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 4,6-Dichloro-1H-pyrrolo[3,2-c]pyridine-2-carboxylic acid (CAS 1256807-21-2), a certified reference material (molecular formula C8H4Cl2N2O2, MW 231.04 g/mol) for analytical method development and quality control.

4,6-Dichloro-1H-pyrrolo[3,2-c]pyridine-2-carboxylic acid (C8H4Cl2N2O2) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 4,6-Dichloro-1H-pyrrolo[3,2-c]pyridine-2-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.
