Description
CATO supplies 7-methoxy-3,4-dihydroisoquinolin-6-ol hydrochloride (CAS 4602-78-2), a certified reference material (molecular formula C10H11NO2HCl, MW 213.66 g/mol) for analytical method development and quality control.
The molecular framework of 7-methoxy-3,4-dihydroisoquinolin-6-ol hydrochloride (C10H11NO2HCl) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), 7-methoxy-3,4-dihydroisoquinolin-6-ol hydrochloride 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.
