Description
CATO manufactures 3-Hydroxy-1-(2-oxo-2-phenylethyl)pyridin-1-ium bromide 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.
3-Hydroxy-1-(2-oxo-2-phenylethyl)pyridin-1-ium bromide (CAS 58309-12-9) is a high-purity analytical reference standard with the molecular formula C13H12NO2Br and a molecular weight of 294.15 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution, 3-Hydroxy-1-(2-oxo-2-phenylethyl)pyridin-1-ium bromide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 294.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
