2-((4-Allyl-5-(pyridin-2-yl)-4H-1,2,4-triazol-3-yl)thio)-N-(2-chloro-4,6-dimethylphenyl)acetamide (CAS 618880-35-6), molecular formula C20H20ClN5OS and molecular weight 413.92 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-((4-Allyl-5-(pyridin-2-yl)-4H-1,2,4-triazol-3-yl)thio)-N-(2-chloro-4,6-dimethylphenyl)acetamide (C20H20ClN5OS) 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 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 413.92 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).
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
