5-Bromo-1-ethyl-1,3-dihydro-2h-indol-2-one (CAS 41192-37-4) is a high-purity analytical reference standard with the molecular formula C10H10BrNO and a molecular weight of 240.10 g/mol.
5-Bromo-1-ethyl-1,3-dihydro-2h-indol-2-one (C10H10BrNO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures 5-Bromo-1-ethyl-1,3-dihydro-2h-indol-2-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.
