Chemical Structure
Description
The occurrence of 6-((2-Chlorophenyl)amino)-2-(methylthio)pyrimidine-4-carboxylic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 6-((2-Chlorophenyl)amino)-2-(methylthio)pyrimidine-4-carboxylic acid (CAS 6307-59-1), a certified reference material (molecular formula C12H10ClN3O2S, MW 295.74 g/mol) for analytical method development and quality control.
The molecular framework of 6-((2-Chlorophenyl)amino)-2-(methylthio)pyrimidine-4-carboxylic acid (C12H10ClN3O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine 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 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.
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.
