Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-[(3,5-Dibromo-4-hydroxy-benzylidene)-hydrazono]-1,3-dihydro-indol-2-one.
CATO supplies 3-[(3,5-Dibromo-4-hydroxy-benzylidene)-hydrazono]-1,3-dihydro-indol-2-one (CAS 454240-99-4), a certified reference material (molecular formula C15H9Br2N3O2, MW 423.06 g/mol) for analytical method development and quality control.
3-[(3,5-Dibromo-4-hydroxy-benzylidene)-hydrazono]-1,3-dihydro-indol-2-one (C15H9Br2N3O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; 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).
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 3-[(3,5-Dibromo-4-hydroxy-benzylidene)-hydrazono]-1,3-dihydro-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.
