Chemical Structure
Description
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
CATO supplies 2-(2-Benzoyl-6,7-dimethoxy-1,2,3,4-tetrahydroisoquinolin-1-yl)acetic acid (CAS 930395-95-2), a certified reference material (molecular formula C20H21NO5, MW 355.38 g/mol) for analytical method development and quality control.
The molecular framework of 2-(2-Benzoyl-6,7-dimethoxy-1,2,3,4-tetrahydroisoquinolin-1-yl)acetic acid (C20H21NO5) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
