Chemical Structure
Description
CATO supplies 3,5-Diiodo-4-hydroxypyridine (CAS 7153-08-4), a certified reference material (molecular formula C5H3I2NO, MW 346.89 g/mol) for analytical method development and quality control.
The molecular framework of 3,5-Diiodo-4-hydroxypyridine (C5H3I2NO) is characterized by an amide group, a hydroxyl group, an ether linkage, iodine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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 3,5-Diiodo-4-hydroxypyridine 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.
