| Hazard Information | Back Directory | 【General Description】
White or very slightly yellow needles. | 【Reactivity Profile】
VANILLIN(121-33-5) can react violently with Br2, HClO4, potassium-tert-butoxide, (tert-chloro-benzene + NaOH), (formic acid + Tl(NO3)3). . VANILLIN(121-33-5) 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). | 【Air & Water Reactions】
Slowly oxidizes on exposure to air. . Slightly water soluble. | 【Fire Hazard】
Flash point data for this chemical are not available, however VANILLIN is probably combustible. |
