Chemical Structure
Description
The occurrence of 4-(1-(3-Chlorophenyl)-6-hydroxy-1H-indazol-3-yl)benzene-1,3-diol is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 4-(1-(3-Chlorophenyl)-6-hydroxy-1H-indazol-3-yl)benzene-1,3-diol (CAS 680610-81-5), a certified reference material (molecular formula C19H13ClN2O3, MW 352.77 g/mol) for analytical method development and quality control.
4-(1-(3-Chlorophenyl)-6-hydroxy-1H-indazol-3-yl)benzene-1,3-diol (C19H13ClN2O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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-(1-(3-Chlorophenyl)-6-hydroxy-1H-indazol-3-yl)benzene-1,3-diol 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.
