Description
Compared with other compounds in its class, the molecular weight of 328.92 g/mol gives 4,6-Dichloro-5-iodoisobenzofuran-1(3H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4,6-Dichloro-5-iodoisobenzofuran-1(3H)-one (CAS 2649788-97-4), molecular formula C8H3Cl2IO2 and molecular weight 328.92 g/mol, is a CATO reference standard with documented purity and traceability.
4,6-Dichloro-5-iodoisobenzofuran-1(3H)-one (C8H3Cl2IO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/iodine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 4,6-Dichloro-5-iodoisobenzofuran-1(3H)-one 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.
