Chemical Structure
Description
3-Chloro-1H-pyrrolo[2,3-b]pyridine-6-carbonitrile (CAS 1190318-95-6), molecular formula C8H4ClN3 and molecular weight 177.59 g/mol, is a CATO reference standard with documented purity and traceability.
3-Chloro-1H-pyrrolo[2,3-b]pyridine-6-carbonitrile (C8H4ClN3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), 3-Chloro-1H-pyrrolo[2,3-b]pyridine-6-carbonitrile 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.
