Chemical Structure
Description
The occurrence of 3-(4-(tert-Butyl)phenyl)-4,5-diphenyl-4H-1,2,4-triazole is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-(4-(tert-Butyl)phenyl)-4,5-diphenyl-4H-1,2,4-triazole (CAS 444153-33-7) is a high-purity analytical reference standard with the molecular formula C24H23N3 and a molecular weight of 353.46 g/mol.
3-(4-(tert-Butyl)phenyl)-4,5-diphenyl-4H-1,2,4-triazole (C24H23N3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
