Chemical Structure
Description
The occurrence of 2-((5-((4-Chlorobenzyl)thio)-1,3,4-thiadiazol-2-yl)thio)-N-(4-ethylphenyl)acetamide 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.
2-((5-((4-Chlorobenzyl)thio)-1,3,4-thiadiazol-2-yl)thio)-N-(4-ethylphenyl)acetamide (CAS 499101-90-5), molecular formula C19H18ClN3OS3 and molecular weight 436.01 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, chlorine substitution, 2-((5-((4-Chlorobenzyl)thio)-1,3,4-thiadiazol-2-yl)thio)-N-(4-ethylphenyl)acetamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 436.01 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.
CATO manufactures 2-((5-((4-Chlorobenzyl)thio)-1,3,4-thiadiazol-2-yl)thio)-N-(4-ethylphenyl)acetamide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
