Chemical Structure
Description
The occurrence of 3-((3,4-Dimethylphenyl)sulfonyl)-N-(4-fluorophenyl)-[1,2,3]triazolo[1,5-a]quinazolin-5-amine is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 3-((3,4-Dimethylphenyl)sulfonyl)-N-(4-fluorophenyl)-[1,2,3]triazolo[1,5-a]quinazolin-5-amine (CAS 866812-71-7), a certified reference material (molecular formula C23H18FN5O2S, MW 447.48 g/mol) for analytical method development and quality control.
3-((3,4-Dimethylphenyl)sulfonyl)-N-(4-fluorophenyl)-[1,2,3]triazolo[1,5-a]quinazolin-5-amine (C23H18FN5O2S) contains a steroid core, an amide group, a sulfone 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).
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.
