Chemical Structure
Description
CATO supplies 2-[(4-bromo-3,5-dimethyl-1h-pyrazol-1-yl)methyl]quinoline-4-carboxylic acid (CAS 956392-62-4), a certified reference material (molecular formula C16H14BrN3O2, MW 360.21 g/mol) for analytical method development and quality control.
The molecular framework of 2-[(4-bromo-3,5-dimethyl-1h-pyrazol-1-yl)methyl]quinoline-4-carboxylic acid (C16H14BrN3O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine 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. 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.
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.
