Chemical Structure
Description
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.
3,4-Dichloro-2-iodoanisole (CAS 873386-93-7), molecular formula C7H5Cl2IO and molecular weight 302.92 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3,4-Dichloro-2-iodoanisole (C7H5Cl2IO) is characterized by a hydroxyl group, an ether linkage, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures 3,4-Dichloro-2-iodoanisole 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.
