4-(2-Hydroxyethyl)-5-methyl-2-phenyl-1-((2-(2,2,2-trifluoroacetyl)-1,2,3,4-tetrahydroisoquinolin-7-yl)sulfonyl)-1,2-dihydro-3H-pyrazol-3-one CAS 861207-34-3

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 4-(2-Hydroxyethyl)-5-methyl-2-phenyl-1-((2-(2,2,2-trifluoroacetyl)-1,2,3,4-tetrahydroisoquinolin-7-yl)sulfonyl)-1,2-dihydro-3H-pyrazol-3-one (CAS 861207-34-3), a certified reference material (molecular formula C23H22F3N3O5S, MW 509.50 g/mol) for analytical method development and quality control.

The molecular framework of 4-(2-Hydroxyethyl)-5-methyl-2-phenyl-1-((2-(2,2,2-trifluoroacetyl)-1,2,3,4-tetrahydroisoquinolin-7-yl)sulfonyl)-1,2-dihydro-3H-pyrazol-3-one (C23H22F3N3O5S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. 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 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).

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.
