Description
CATO manufactures 1-Isothiocyanato-4-[(trifluoromethyl)thio]benzene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
1-Isothiocyanato-4-[(trifluoromethyl)thio]benzene (CAS 189281-95-6) is a high-purity analytical reference standard with the molecular formula C8H4F3NS2 and a molecular weight of 235.25 g/mol.
1-Isothiocyanato-4-[(trifluoromethyl)thio]benzene (C8H4F3NS2) 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
