Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies (R)-1-(6,7-Dimethoxy-1-methyl-3,4-dihydroisoquinolin-2(1H)-yl)ethanone (CAS 143261-75-0), a certified reference material (molecular formula C14H19NO3, MW 249.31 g/mol) for analytical method development and quality control.
The molecular framework of (R)-1-(6,7-Dimethoxy-1-methyl-3,4-dihydroisoquinolin-2(1H)-yl)ethanone (C14H19NO3) 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).
As a certified reference material (CRM), (R)-1-(6,7-Dimethoxy-1-methyl-3,4-dihydroisoquinolin-2(1H)-yl)ethanone 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.
