Chemical Structure
Description
The molecular framework of 5,5,8,8-Tetramethyl-5,6,7,8-tetrahydronaphthalene-2,3-dicarbaldehyde (C16H20O2) 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).
5,5,8,8-Tetramethyl-5,6,7,8-tetrahydronaphthalene-2,3-dicarbaldehyde (CAS 58848-22-9), molecular formula C16H20O2 and molecular weight 244.33 g/mol, is a CATO reference standard with documented purity and traceability.
