CATO supplies 2-((2-Chlorophenyl)thio)-N-(5-(trifluoromethyl)-1,3,4-thiadiazol-2-yl)acetamide (CAS 339013-82-0), a certified reference material (molecular formula C11H7ClF3N3OS2, MW 353.77 g/mol) for analytical method development and quality control.
Structurally, 2-((2-Chlorophenyl)thio)-N-(5-(trifluoromethyl)-1,3,4-thiadiazol-2-yl)acetamide (C11H7ClF3N3OS2) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 353.77 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
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.
