2-Chloro-4-fluoro-5-iodophenol CAS 148254-33-5

Description

Compared with other compounds in its class, the molecular weight of 272.44 g/mol gives 2-Chloro-4-fluoro-5-iodophenol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-Chloro-4-fluoro-5-iodophenol (CAS 148254-33-5), molecular formula C6H3ClFIO and molecular weight 272.44 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 2-Chloro-4-fluoro-5-iodophenol (C6H3ClFIO) is characterized by a hydroxyl group, an ether linkage, fluorine/chlorine/iodine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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-Chloro-4-fluoro-5-iodophenol 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.
