Chemical Structure
Description
1,2,3,4-Tetrachloro-5-iodobenzene (CAS 38411-21-1), molecular formula C6HCl4I and molecular weight 341.79 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to chlorine/iodine substitution, an aromatic ring system, 1,2,3,4-Tetrachloro-5-iodobenzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 341.79 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 1,2,3,4-Tetrachloro-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.
