Chemical Structure
Description
The occurrence of N-(3,4-dichlorophenyl)-2-((5-(m-tolyl)-1,3,4-oxadiazol-2-yl)thio)acetamide is closely related to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
N-(3,4-dichlorophenyl)-2-((5-(m-tolyl)-1,3,4-oxadiazol-2-yl)thio)acetamide (CAS 332380-82-2), molecular formula C17H13Cl2N3O2S and molecular weight 394.28 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N-(3,4-dichlorophenyl)-2-((5-(m-tolyl)-1,3,4-oxadiazol-2-yl)thio)acetamide (C17H13Cl2N3O2S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
