Chemical Structure
Description
1,1-Ethylidenebis[2,3-dichloro-4-methoxy-benzene (C16H14Cl4O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
1,1-Ethylidenebis[2,3-dichloro-4-methoxy-benzene (CAS 397301-41-6) is a high-purity analytical reference standard with the molecular formula C16H14Cl4O2 and a molecular weight of 380.09 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.
