Chemical Structure

3-(5-((4-(Tert-butyl)benzyl)thio)-4-ethyl-4H-1,2,4-triazol-3-yl)-1-(4-chlorophenyl)pyridazin-4(1H)-one CAS 478077-64-4 chemical structure

Description

The occurrence of 3-(5-((4-(Tert-butyl)benzyl)thio)-4-ethyl-4H-1,2,4-triazol-3-yl)-1-(4-chlorophenyl)pyridazin-4(1H)-one is closely related to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-(5-((4-(Tert-butyl)benzyl)thio)-4-ethyl-4H-1,2,4-triazol-3-yl)-1-(4-chlorophenyl)pyridazin-4(1H)-one (CAS 478077-64-4), molecular formula C25H26ClN5OS and molecular weight 480.02 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 3-(5-((4-(Tert-butyl)benzyl)thio)-4-ethyl-4H-1,2,4-triazol-3-yl)-1-(4-chlorophenyl)pyridazin-4(1H)-one (C25H26ClN5OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 480.02 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.
