Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2,3,4-Trifluorophenyl isothiocyanate (CAS 119474-40-7), molecular formula C7H2F3NS and molecular weight 189.16 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2,3,4-Trifluorophenyl isothiocyanate (C7H2F3NS) contains a nitrile group, sulfur-containing functionality, fluorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 189.16 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
CATO manufactures 2,3,4-Trifluorophenyl isothiocyanate 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.
