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 6,8-Dimethoxy-1,3-dimethylisoquinoline.
CATO supplies 6,8-Dimethoxy-1,3-dimethylisoquinoline (CAS 66178-59-4), a certified reference material (molecular formula C13H15NO2, MW 217.26 g/mol) for analytical method development and quality control.
The molecular framework of 6,8-Dimethoxy-1,3-dimethylisoquinoline (C13H15NO2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 6,8-Dimethoxy-1,3-dimethylisoquinoline under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
