Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 180.99 g/mol gives 2,3-Dichloro-4-fluorophenol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2,3-Dichloro-4-fluorophenol (CAS 934180-45-7), molecular formula C6H3Cl2FO and molecular weight 180.99 g/mol, is a CATO reference standard with documented purity and traceability.
2,3-Dichloro-4-fluorophenol (C6H3Cl2FO) contains a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
CATO manufactures 2,3-Dichloro-4-fluorophenol 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.
