Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-[(4-Formyl-2-iodo-6-methoxyphenoxy)methyl]benzoic acid.
4-[(4-Formyl-2-iodo-6-methoxyphenoxy)methyl]benzoic acid (CAS 428498-47-9) is a high-purity analytical reference standard with the molecular formula C16H13IO5 and a molecular weight of 412.18 g/mol.
4-[(4-Formyl-2-iodo-6-methoxyphenoxy)methyl]benzoic acid (C16H13IO5) contains a flavonoid core, a hydroxyl group, an ether linkage, iodine substitution. 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-[(4-Formyl-2-iodo-6-methoxyphenoxy)methyl]benzoic 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.
