Chemical Structure
Description
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.
5-[(4-Fluorophenyl)sulfanyl]-4-methyl-1,2,3-thiadiazole (CAS 338978-80-6), molecular formula C9H7FN2S2 and molecular weight 226.29 g/mol, is a CATO reference standard with documented purity and traceability.
5-[(4-Fluorophenyl)sulfanyl]-4-methyl-1,2,3-thiadiazole (C9H7FN2S2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
