Chemical Structure
Description
The occurrence of 3-(3-Chlorophenyl)-6,7-diphenyl-2H-oxazolo[3,2-a][1,3,5]triazine-2,4(3H)-dione is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-(3-Chlorophenyl)-6,7-diphenyl-2H-oxazolo[3,2-a][1,3,5]triazine-2,4(3H)-dione (CAS 35629-67-5) is a high-purity analytical reference standard with the molecular formula C23H14ClN3O3 and a molecular weight of 415.83 g/mol.
3-(3-Chlorophenyl)-6,7-diphenyl-2H-oxazolo[3,2-a][1,3,5]triazine-2,4(3H)-dione (C23H14ClN3O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, 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.
