Specification

1. Introduction of Veratraldehyde
Veratraldehyde is derivative of vanillin, widely used as a flavorant and odorant. The IUPAC name of Veratraldehyde is 3,4-dimethoxybenzaldehyde, it is off-white crystalline solid. It is also called 3,4-dimethoxy-benzaldehyd ; 4-O-Methylvanillin ; Benzaldehyde, 3,4-dimethoxy-veratraldehyde ; Protocatechuecaldehyde dimethyl ether ; Protocatechuecaldehydedimethylether ; P-Veratric aldehyde ; P-veratricaldehyde and so on.

2. Properties of Veratraldehyde
Veratraldehyde is incompatible with strong oxidizing agents and strong bases.Veratraldehyde is an aldehyde. Aldehydes are readily oxidized to give carboxylic acids. Flammable and/or toxic gases are generated by the combination of aldehydes with azo, diazo compounds, dithiocarbamates, nitrides, and strong reducing agents. Aldehydes can react with air to give first peroxo acids, and ultimately carboxylic acids. These autoxidation reactions are activated by light, catalyzed by salts of transition metals, and are autocatalytic (catalyzed by the products of the reaction).
