Veratraldehyde(Cas 120-14-9) Usage
|
Chemical properties |
White to brown or blue-gray needle crystal (crystallization in ether); sweet woody fragrance, fragrant grass aroma and strong flavor of vanilla blue; oxidized into odorless 3,4-dimethoxybenzoic acid (veratric acid) in the air; Melting point 43~45℃; Insoluble in cold water; soluble in hot water, ethanol and oil. Natural products exist in the Java citronella oil and Hu Xanthium parsley oil and so on. Use GB 2760 a 1996 provisions for the use of food spices. |
|
Application |
This product is the intermediate of organic synthesis. In pharmaceutical industry, it is used to synthesize methamphetamine and also used in the production of veterinary drug sulfonamide synergist. Adding 0.02% (weight) of this veterinary drug into feed can increase the efficiency of the iodine drug synergistic added in feed, which can prevent and control the poultry bacterial infection. Used as pharmaceutical intermediate and mainly used for antibiotic drug synthesis. |
|
Preparation |
It can be derived from the reaction of 3-methoxy-4-hydroxybenzaldehyde (vanillin) and dimethyl sulfate, or derived from the methylation of dimethyl sulfate with vanillin in alkaline conditions. |
|
Aroma threshold values |
Aroma characteristics at 1.0%: phenolic, sweet vanilla, powdery, slightly woody with a candy and cocoa creaminess. |
|
Taste threshold values |
Taste characteristics at 50 ppm: phenolic, vanilla, sweet powdery cocoa, creamy, cherry-like with phenolic and balsamic nuances.. |

General Description |
Needles or chunky light peach powder. Has an odor of vanilla beans. |
|
Air & Water Reactions |
Insoluble in water. |
|
Reactivity Profile |
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). |
|
Fire Hazard |
Veratraldehyde is probably combustible. |
|
Flammability and Explosibility |
Notclassified |
|
Biochem/physiol Actions |
Taste at 50 ppm |
|
Purification Methods |
Crystallise the ether from diethyl ether, pet ether, CCl4 or toluene. [Beilstein 8 IV 1765.] |
