Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Chloro-2-(1-(phenylsulfonyl)-3-(1H-1,2,4-triazol-5-yl)propyl)-5-(trifluoromethyl)pyridine.
3-Chloro-2-(1-(phenylsulfonyl)-3-(1H-1,2,4-triazol-5-yl)propyl)-5-(trifluoromethyl)pyridine (CAS 338420-82-9), molecular formula C17H14ClF3N4O2S and molecular weight 430.83 g/mol, is a CATO reference standard with documented purity and traceability.
3-Chloro-2-(1-(phenylsulfonyl)-3-(1H-1,2,4-triazol-5-yl)propyl)-5-(trifluoromethyl)pyridine (C17H14ClF3N4O2S) contains a steroid core, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
