Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
(3Z)-3-{[1-(4-bromophenyl)-1H-pyrrol-3-yl]methylidene}-2,3-dihydro-1H-indol-2-one (CAS 691869-05-3) is a high-purity analytical reference standard with the molecular formula C19H13BrN2O and a molecular weight of 365.22 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution, (3Z)-3-{[1-(4-bromophenyl)-1H-pyrrol-3-yl]methylidene}-2,3-dihydro-1H-indol-2-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 365.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
