Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 173.21 g/mol gives 7-Methoxy-1-methylisoquinoline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
7-Methoxy-1-methylisoquinoline (CAS 76143-84-5), molecular formula C11H11NO and molecular weight 173.21 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 7-Methoxy-1-methylisoquinoline is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 173.21 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), 7-Methoxy-1-methylisoquinoline 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.
