Chemical Structure
Description
The occurrence of 5-Chloro-2-iodobenzoic Acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/iodine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 5-Chloro-2-iodobenzoic Acid (CAS 13421-00-6), a certified reference material (molecular formula C7H4ClIO2, MW 282.46 g/mol) for analytical method development and quality control.
5-Chloro-2-iodobenzoic Acid (C7H4ClIO2) 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. 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 5-Chloro-2-iodobenzoic Acid 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.
