Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 6,7-Dimethoxy-1-(4-nitrobenzyl)-3,4-dihydroisoquinoline.
6,7-Dimethoxy-1-(4-nitrobenzyl)-3,4-dihydroisoquinoline (CAS 10268-39-0), molecular formula C7H7Cl2F4NO2 and molecular weight 284.04 g/mol, is a CATO reference standard with documented purity and traceability.
6,7-Dimethoxy-1-(4-nitrobenzyl)-3,4-dihydroisoquinoline (C7H7Cl2F4NO2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), 6,7-Dimethoxy-1-(4-nitrobenzyl)-3,4-dihydroisoquinoline 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.
