Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Chloro-2,4,5,6-tetrafluorobenzoylchloride.
3-Chloro-2,4,5,6-tetrafluorobenzoylchloride (CAS 292621-58-0), molecular formula C7Cl2F4O and molecular weight 246.97 g/mol, is a CATO reference standard with documented purity and traceability.
3-Chloro-2,4,5,6-tetrafluorobenzoylchloride (C7Cl2F4O) 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 3-Chloro-2,4,5,6-tetrafluorobenzoylchloride 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.
