3-Ethynylisoquinoline (CAS 86520-97-0), molecular formula C11H7N and molecular weight 153.18 g/mol, is a CATO reference standard with documented purity and traceability.
3-Ethynylisoquinoline (C11H7N) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. 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), 3-Ethynylisoquinoline 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.
