Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
CATO supplies 2-(4-Bromophenyl)-1-(4-chlorophenyl)-6,6-dimethyl-1,5,6,7-tetrahydro-4H-indol-4-one (CAS 902469-90-3), a certified reference material (molecular formula C22H19BrClNO, MW 428.75 g/mol) for analytical method development and quality control.
The molecular framework of 2-(4-Bromophenyl)-1-(4-chlorophenyl)-6,6-dimethyl-1,5,6,7-tetrahydro-4H-indol-4-one (C22H19BrClNO) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
