Chemical Structure
Description
0031AC 2-(Methylsulfinyl)-5-(trifluoromethyl)-1,3,4-thiadiazole 65439-30-7 C4H3F3N2OS2 (CAS 65439-30-7) is a high-purity analytical reference standard with the molecular formula C4H3F3N2OS2 and a molecular weight of 216.20 g/mol.
Structurally, 0031AC 2-(Methylsulfinyl)-5-(trifluoromethyl)-1,3,4-thiadiazole 65439-30-7 C4H3F3N2OS2 (C4H3F3N2OS2) contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 216.20 g/mol, it falls into the medium-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.
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.
