Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7-(Trifluoromethyl)benzo[d]isothiazole.
7-(Trifluoromethyl)benzo[d]isothiazole (CAS 1783747-88-5), molecular formula C8H4F3NS and molecular weight 203.18 g/mol, is a CATO reference standard with documented purity and traceability.
7-(Trifluoromethyl)benzo[d]isothiazole (C8H4F3NS) 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.
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.
