2-((4-Amino-5-(pyridin-4-yl)-4H-1,2,4-triazol-3-yl)thio)-N-(4-phenoxyphenyl)acetamide (CAS 573950-10-4), molecular formula C21H18N6O2S and molecular weight 418.47 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-((4-Amino-5-(pyridin-4-yl)-4H-1,2,4-triazol-3-yl)thio)-N-(4-phenoxyphenyl)acetamide (C21H18N6O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 16.0, corresponding to approximately 16 ring(s) or double-bond equivalent(s). With a molecular weight of 418.47 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
