Chemical Structure
Description
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.
3-Chloro-2-({7-[(Z)-2-(4-chlorophenyl)ethenyl]-[1,2,4]triazolo[1,5-a]pyrimidin-2-yl}sulfanyl)-5-(trifluoromethyl)pyridine (CAS 477885-63-5), molecular formula C19H10Cl2F3N5S and molecular weight 468.28 g/mol, is a CATO reference standard with documented purity and traceability.
3-Chloro-2-({7-[(Z)-2-(4-chlorophenyl)ethenyl]-[1,2,4]triazolo[1,5-a]pyrimidin-2-yl}sulfanyl)-5-(trifluoromethyl)pyridine (C19H10Cl2F3N5S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point; 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).
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.
