Description
Compared with other compounds in its class, the molecular weight of 383.77 g/mol gives 1-(3-Chloro-5-(trifluoromethyl)pyridin-2-yl)-N-(2-methoxyethyl)-1H-pyrrole-2-sulfonamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 1-(3-Chloro-5-(trifluoromethyl)pyridin-2-yl)-N-(2-methoxyethyl)-1H-pyrrole-2-sulfonamide (CAS 321433-69-6), a certified reference material (molecular formula C13H13ClF3N3O3S, MW 383.77 g/mol) for analytical method development and quality control.
1-(3-Chloro-5-(trifluoromethyl)pyridin-2-yl)-N-(2-methoxyethyl)-1H-pyrrole-2-sulfonamide (C13H13ClF3N3O3S) 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.
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.
