Description

Compared with other compounds in its class, the molecular weight of 359.26 g/mol gives 3-(3-Nitrophenyl)-5-(trifluoromethyl)-[1,2,4]triazolo[4,3-c]quinazoline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-(3-Nitrophenyl)-5-(trifluoromethyl)-[1,2,4]triazolo[4,3-c]quinazoline (CAS 303149-04-4), molecular formula C16H8F3N5O2 and molecular weight 359.26 g/mol, is a CATO reference standard with documented purity and traceability.

3-(3-Nitrophenyl)-5-(trifluoromethyl)-[1,2,4]triazolo[4,3-c]quinazoline (C16H8F3N5O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine 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).

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.
