Description
5-Bromo-1-((5-(2-chlorophenyl)-3-(4-methoxyphenyl)-4,5-dihydro-1H-pyrazol-1-yl)methyl)indoline-2,3-dione (CAS 337932-35-1) is a high-purity analytical reference standard with the molecular formula C25H19BrClN3O3 and a molecular weight of 524.79 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine/bromine substitution, 5-Bromo-1-((5-(2-chlorophenyl)-3-(4-methoxyphenyl)-4,5-dihydro-1H-pyrazol-1-yl)methyl)indoline-2,3-dione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 524.79 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
