Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies Benzoic acid, p-(dichloroiodo)- (8CI) (CAS 22695-77-8), a certified reference material (molecular formula C7H4Cl2IO2H, MW 318.92 g/mol) for analytical method development and quality control.
Benzoic acid, p-(dichloroiodo)- (8CI) (C7H4Cl2IO2H) 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.
As a certified reference material (CRM), Benzoic acid, p-(dichloroiodo)- (8CI) meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
