Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3,4-di(tert-butyl)-2-(3-chloro-4-fluoroanilino)-1,3-thiazol-3-ium bromide (CAS 849066-35-9) is a high-purity analytical reference standard with the molecular formula C17H23ClFN2SBr and a molecular weight of 421.80 g/mol.
3,4-di(tert-butyl)-2-(3-chloro-4-fluoroanilino)-1,3-thiazol-3-ium bromide (C17H23ClFN2SBr) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine/chlorine/bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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).
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.
