5-Chloro-3-(2,2-dimethylpropyl)-1,2,4-thiadiazole (CAS 1479078-15-3) is a high-purity analytical reference standard with the molecular formula C7H11ClN2S and a molecular weight of 190.69 g/mol.
5-Chloro-3-(2,2-dimethylpropyl)-1,2,4-thiadiazole (C7H11ClN2S) contains a nitrile group, sulfur-containing functionality, chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
