Chemical Structure
Description
The occurrence of 1-Chloro-5,7-dimethyl-3,4-dihydronaphthalene-2-carbaldehyde is closely related to a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 1-Chloro-5,7-dimethyl-3,4-dihydronaphthalene-2-carbaldehyde (CAS 443305-29-1), a certified reference material (molecular formula C13H13ClO, MW 220.69 g/mol) for analytical method development and quality control.
1-Chloro-5,7-dimethyl-3,4-dihydronaphthalene-2-carbaldehyde (C13H13ClO) contains a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
