Chemical Structure
Description
The molecular framework of 3,7-Dihydroxy-s-indacene-1,5-dione (C12H6O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring 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 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).
3,7-Dihydroxy-s-indacene-1,5-dione (CAS 371220-36-9) is a high-purity analytical reference standard with the molecular formula C12H6O4 and a molecular weight of 214.17 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
