2,5-Dimethoxybenzaldehyde ke phofo e khanyang ea kristale e mosehla e boima ba molek'hule ea 166.18 le ntlha e belang ea 146 ° C. E qhibiliha ka har'a metsoako ea tlhaho e kang ethanol le ether. E sebelisoa haholo-holo e le setsi sa meriana.

Ntle le ho ba oxidized kapa ho fokotsoa ho 2,5-dimethoxybenzoic acid, benzonitrile kapa benzyl joala, 2,5-dimethoxybenzaldehyde ka boeona le eona e na le boleng bo ikhethang ba ts'ebeliso. Ka ho sebetsana le lintho tse nang le mefuta e fapaneng ea lihlopha tse sebetsang, limolek'hule tsa lithethefatsi tse nang le mekhoa e fapaneng le liphello tse fapaneng li ka fumanoa.
