Chemical Structure
Description
3-Methylisoquinoline-5-carbonitrile (CAS 99974-21-7), molecular formula C11H8N2 and molecular weight 168.19 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 3-Methylisoquinoline-5-carbonitrile is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 168.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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-Methylisoquinoline-5-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.
