Compared with other compounds in its class, the molecular weight of 751.60 g/mol gives 2,3,4,5,6-Pentaiodobenzoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2,3,4,5,6-Pentaiodobenzoic acid (CAS 64385-02-0), molecular formula C7HI5O2 and molecular weight 751.60 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2,3,4,5,6-Pentaiodobenzoic acid (C7HI5O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, 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 2,3,4,5,6-Pentaiodobenzoic acid 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.
