Chemical Structure
Description
Structurally, 1-Phenyl-3-[(5-phenyl-1H-1,2,4-triazol-3-yl)methoxy]-1H-1,2,4-triazole (C17H14N6O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 318.33 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
1-Phenyl-3-[(5-phenyl-1H-1,2,4-triazol-3-yl)methoxy]-1H-1,2,4-triazole (CAS 338405-36-0), molecular formula C17H14N6O and molecular weight 318.33 g/mol, is a CATO reference standard with documented purity and traceability.
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.
