Description
CATO manufactures 3-Chloro-5-iodobenzoyl chloride 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.
3-Chloro-5-iodobenzoyl chloride (CAS 1261730-81-7) is a high-purity analytical reference standard with the molecular formula C7H3Cl2IO and a molecular weight of 300.91 g/mol.
3-Chloro-5-iodobenzoyl chloride (C7H3Cl2IO) contains a hydroxyl group, an ether linkage, chlorine/iodine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
