The molecular framework of 1146-98-1 OQZ7BND2QN Bromindione Bromindione [USAN:INN:BAN] 2-p-Bromophenylindandione 1,3-Indandione, 2-(p-bromophenyl)- 1H-Indene-1,3(2H)-dione, 2-(4-bromophenyl)- M.G. 2555 4-07-00-02572 (Beilstein Handbook Reference) BRN 1878512 Bromindiona [INN-Spanish] p-Bromindione Bromindionum [INN-Latin] 2-(4-Bromofenil)-1,3-indandione [Italian] Bromophenindione 2-(p-Bromophenyl)-1,3-indandione 2-(4-Bromophenyl)-1,3-indandione p-Bromphenylindandione Haldinone Halinone HL 255 MG 2555 Fluidane 2-(4-Bromofenil)-1,3-indandione Bromindiona Bromindionum UNII-OQZ7BND2QN (C15H9BrO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, a polycyclic aromatic system. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
