Chemical Structure
Description
The occurrence of Dimethyl 7-(propan-2-ylidene)bicyclo[2.2.1]hepta-2,5-diene-2,3-dicarboxylate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Dimethyl 7-(propan-2-ylidene)bicyclo[2.2.1]hepta-2,5-diene-2,3-dicarboxylate (CAS 19019-88-6) is a high-purity analytical reference standard with the molecular formula C14H16O4 and a molecular weight of 248.27 g/mol.
The molecular framework of Dimethyl 7-(propan-2-ylidene)bicyclo[2.2.1]hepta-2,5-diene-2,3-dicarboxylate (C14H16O4) 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).
