Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
5-Ethyl-5-hydroxy-1-methyl-4-phenyl-1H-pyrrol-2(5H)-one (CAS 637332-40-2) is a high-purity analytical reference standard with the molecular formula C13H15NO2 and a molecular weight of 217.26 g/mol.
5-Ethyl-5-hydroxy-1-methyl-4-phenyl-1H-pyrrol-2(5H)-one (C13H15NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO manufactures 5-Ethyl-5-hydroxy-1-methyl-4-phenyl-1H-pyrrol-2(5H)-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.
