Chemical Structure
Description
Structurally, 4940-39-0 FY38S0790W Chromocarb [INN:DCF] Chromone-2-carboxylic acid 4H-1-Benzopyran-2-carboxylic acid, 4-oxo- 4-Oxo-4H-1-benzopyran-2-carboxylic acid 4-Oxo-4H-chromene-2-carboxylic acid 5-18-08-00312 (Beilstein Handbook Reference) Atremon BRN 0146442 Chromocarb Chromocarbe [INN-French] Chromocarbum [INN-Latin] Chromonecarboxylic acid Cromocarbo [INN-Spanish] EINECS 225-583-0 LP-1 Chromocarbe Chromocarbum Cromocarbo UNII-FY38S0790W (C10H12O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 196.20 g/mol, it falls into the medium-molecular-weight range. 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).
