Chemical Structure
Description
The molecular framework of (3S)-2-Carbobenzoxy-1,2,3,4-tetrahydroisoquinoline-3-carboxylic Acid (C18H17NO4) 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).
CATO supplies (3S)-2-Carbobenzoxy-1,2,3,4-tetrahydroisoquinoline-3-carboxylic Acid (CAS 79261-58-8), a certified reference material (molecular formula C18H17NO4, MW 311.33 g/mol) for analytical method development and quality control.
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.
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.
