Chemical Structure
Description
The occurrence of 1-(Hydroxymethyl)-6-methoxyisoquinolin-7-ol is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 1-(Hydroxymethyl)-6-methoxyisoquinolin-7-ol (CAS 677725-58-5), a certified reference material (molecular formula C11H11NO3, MW 205.21 g/mol) for analytical method development and quality control.
The molecular framework of 1-(Hydroxymethyl)-6-methoxyisoquinolin-7-ol (C11H11NO3) is characterized by an amino-acid-derived structure, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
CATO manufactures 1-(Hydroxymethyl)-6-methoxyisoquinolin-7-ol 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.
