CATO supplies GDK3KY5FCU 329306-27-6 Lirimilast [INN] 2-(2,4-Dichlorobenzoyl)-3-ureidobenzofuran-6-yl methanesulfonate Lirimilast UNII-GDK3KY5FCU (CAS 329306-27-6), a certified reference material (molecular formula C17H12Cl2N2O6S, MW 443.26 g/mol) for analytical method development and quality control.
The molecular framework of GDK3KY5FCU 329306-27-6 Lirimilast [INN] 2-(2,4-Dichlorobenzoyl)-3-ureidobenzofuran-6-yl methanesulfonate Lirimilast UNII-GDK3KY5FCU (C17H12Cl2N2O6S) is characterized by a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine 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. 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.
