Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 200.52 g/mol gives 4-Chloro-2,3,5,6-tetrafluorophenol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-Chloro-2,3,5,6-tetrafluorophenol (CAS 4232-66-0), molecular formula C6HClF4O and molecular weight 200.52 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system, 4-Chloro-2,3,5,6-tetrafluorophenol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 200.52 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
CATO manufactures 4-Chloro-2,3,5,6-tetrafluorophenol 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.
