Chemical Structure
Description
The occurrence of 3-Chloro-2-(2-(methylthio)-1H-imidazol-1-yl)-5-(trifluoromethyl)pyridine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 3-Chloro-2-(2-(methylthio)-1H-imidazol-1-yl)-5-(trifluoromethyl)pyridine (CAS 338956-48-2), a certified reference material (molecular formula C10H7ClF3N3S, MW 293.70 g/mol) for analytical method development and quality control.
3-Chloro-2-(2-(methylthio)-1H-imidazol-1-yl)-5-(trifluoromethyl)pyridine (C10H7ClF3N3S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
