Description
1823182-41-7 2-((8-chloro-6-(trifluoromethyl)-[1,2,4]triazolo[4,3-a]pyridin-3-yl)thio)acetic acid KS-000025N8 (C9H5ClF3N3O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO supplies 1823182-41-7 2-((8-chloro-6-(trifluoromethyl)-[1,2,4]triazolo[4,3-a]pyridin-3-yl)thio)acetic acid KS-000025N8 (CAS 1823182-41-7), a certified reference material (molecular formula C9H5ClF3N3O2S, MW 311.67 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.
