Description
CATO manufactures 3-Chloro-2,4-difluorophenylisothiocyanate 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.
3-Chloro-2,4-difluorophenylisothiocyanate (CAS 1713163-05-3) is a high-purity analytical reference standard with the molecular formula C7H2ClF2NS and a molecular weight of 205.61 g/mol.
The molecular framework of 3-Chloro-2,4-difluorophenylisothiocyanate (C7H2ClF2NS) is characterized by a nitrile group, sulfur-containing functionality, fluorine/chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
