Chemical Structure
Description
CATO supplies (hydroxy(pyridin-4-yl)methyl)phosphonic acid (CAS 5422-73-1), a certified reference material (molecular formula C6H8NO4P, MW 189.11 g/mol) for analytical method development and quality control.
Owing to an amide group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, (hydroxy(pyridin-4-yl)methyl)phosphonic acid is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 189.11 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 (hydroxy(pyridin-4-yl)methyl)phosphonic 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.
