Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-Chloro-7-methyl-6,7-dihydro-5H-cyclopenta[b]pyridine-3-carbonitrile (CAS 1491499-01-4), molecular formula C10H9ClN2 and molecular weight 192.64 g/mol, is a CATO reference standard with documented purity and traceability.
2-Chloro-7-methyl-6,7-dihydro-5H-cyclopenta[b]pyridine-3-carbonitrile (C10H9ClN2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), 2-Chloro-7-methyl-6,7-dihydro-5H-cyclopenta[b]pyridine-3-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.
