Synthesis Reference(s)

Journal of the American Chemical Society, 69, p. 2070, 1947 DOI: 10.1021/ja01200a517Organic Syntheses, Coll. Vol. 2, p. 619, 1943Tetrahedron Letters, 20, p. 975, 1979

Chemical Properties

Veratraldehyde is a crystalline solid (mp 44.5–45°C) with a woody, vanillalike odor. Veratraldehyde can be prepared by methylation of vanillin. It is used in oriental and warm, woody fragrances, as well as in flavor compositions for vanilla notes. It is an intermediate in, for example, the synthesis of pharmaceuticals.

Taste threshold values

Taste characteristics at 50 ppm: phenolic, vanilla, sweet powdery cocoa, creamy, cherry-like with phenolic and balsamic nuances..

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).

Aroma threshold values

Aroma characteristics at 1.0%: phenolic, sweet vanilla, powdery, slightly woody with a candy and cocoa creaminess.

Occurrence

Reported among the constituents of the essential oils of Cymbopogon javanensis and Eryngium poterium. Also reported found in raspberry, ginger, peppermint oil, Bourbon vanilla and mastic gum oil.

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.

Chemical Properties

Veratraldehyde has a very sweet, woody, vanilla-like odor with a warm, sweet, vanilla-like taste. This compound gets oxidized in air to odorless veratric acid.

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.

Chemical Properties

off-white crystalline solid

Purification Methods

Crystallise the ether from diethyl ether, pet ether, CCl4 or toluene. [Beilstein 8 IV 1765.]

General Description

Needles or chunky light peach powder. Has an odor of vanilla beans.

Fire Hazard

Veratraldehyde is probably combustible.

Preparation

Prepared from vanillin by methylation of vanillin with dimethylsulfate under mildly alkaline conditions.

Air & Water Reactions

Insoluble in water.

Degradation of Veratraldehyde (cas 120-14-9) by Alcaligenes paradoxus08/28/2019

The degradation of veratraldehyde by Alcaligenes paradoxus was studied. Three products, veratric acid, vanillic acid and a minor amount of veratryl alcohol, were identified. The effect of various metabolic inhibitors on the uptake of veratraldehyde, veratric and vanillic acid showed the uptake p...detailed
