Chemical Structure
Description
The molecular framework of 2-Acetyl-2,3,3a,9a-tetrahydronaphtho[2,3-b]furan-4,9-dione (C14H10O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, 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 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).
2-Acetyl-2,3,3a,9a-tetrahydronaphtho[2,3-b]furan-4,9-dione (CAS 1134099-70-9) is a high-purity analytical reference standard with the molecular formula C14H10O4 and a molecular weight of 242.23 g/mol.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
