Chemical Structure
Description
The occurrence of N-(4-Ethoxyphenyl)-2-((4-(4-ethoxyphenyl)-5-(pyridin-3-yl)-4H-1,2,4-triazol-3-yl)thio)acetamide is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
N-(4-Ethoxyphenyl)-2-((4-(4-ethoxyphenyl)-5-(pyridin-3-yl)-4H-1,2,4-triazol-3-yl)thio)acetamide (CAS 477329-73-0) is a high-purity analytical reference standard with the molecular formula C25H25N5O3S and a molecular weight of 475.56 g/mol.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, N-(4-Ethoxyphenyl)-2-((4-(4-ethoxyphenyl)-5-(pyridin-3-yl)-4H-1,2,4-triazol-3-yl)thio)acetamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 475.56 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
