Chemical Structure
Description
1,2-Dimethyl-4-fluoro-5-iodobenzene (CAS 905275-28-7) is a high-purity analytical reference standard with the molecular formula C8H8FI and a molecular weight of 250.05 g/mol.
The molecular framework of 1,2-Dimethyl-4-fluoro-5-iodobenzene (C8H8FI) is characterized by fluorine/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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 1,2-Dimethyl-4-fluoro-5-iodobenzene 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.
