Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Ethyl 8-cyclohexyl-4-hydroxyquinoline-3-carboxylate (CAS 55376-64-2) is a high-purity analytical reference standard with the molecular formula C18H21NO3 and a molecular weight of 299.36 g/mol.
Ethyl 8-cyclohexyl-4-hydroxyquinoline-3-carboxylate (C18H21NO3) contains a steroid core, 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 Ethyl 8-cyclohexyl-4-hydroxyquinoline-3-carboxylate 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.
