Chemical Structure
Description
CATO supplies 4-(4-((Ethylamino)methyl)phenyl)-5-hydroxyisoquinolin-1(2H)-one (CAS 651029-33-3), a certified reference material (molecular formula C18H18N2O2, MW 294.35 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 4-(4-((Ethylamino)methyl)phenyl)-5-hydroxyisoquinolin-1(2H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 294.35 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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-((Ethylamino)methyl)phenyl)-5-hydroxyisoquinolin-1(2H)-one 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.
