Ethyl vanillin Usage And Synthesis
Chemical Properties WHITE TO OFF-WHITE FINE CRYSTALLINE POWDER
Usage flavoring agent
General Description Colorless crystals. More intense vanilla odor and taste than vanillin.
Air & Water Reactions Slightly water soluble .
Reactivity Profile Protect from light. 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). The addition of stabilizers (antioxidants) to shipments of aldehydes retards autoxidation.
Health Hazard ACUTE/CHRONIC HAZARDS: Toxic. May cause irritation on contact.
Fire Hazard Combustible
