Chemical Structure
Description
The occurrence of (3-Methoxyphenyl)methyl chloroformate is closely related to a carboxylic acid group, 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.
(3-Methoxyphenyl)methyl chloroformate (CAS 81228-89-9) is a high-purity analytical reference standard with the molecular formula C9H9ClO3 and a molecular weight of 200.62 g/mol.
(3-Methoxyphenyl)methyl chloroformate (C9H9ClO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).
