Indole powder is also known as "azaindene". Molecular formula C8H7N, molecular weight 117.15, found in dung, coal tar, jasmine oil, neroli oil. Colourless leafy or plate-like crystals.

Extremely strong dung odour, Indole CAS 120-72-9 diluted with fresh floral scent. Melting point 52°C. Boiling point 253～254°C. Indole Raw Materials Soluble in hot water, benzene and petroleum Ying, soluble in ethanol, ether and methanol.

Applications / Functions of Indole powder

• GB2760 a 96 regulations for the permitted use of edible spices, Indole powder is mainly used to formulate cheese, citrus, coffee, nuts, grapes, strawberries, raspberries, chocolate, mixed fruit, jasmine and lily and other flavours.
• Indole CAS 120-72-9 Used as a reagent for the determination of nitrite, also used in the manufacture of spices and pharmaceuticals.
• Raw material for flavouring, pharmaceuticals, phytohormone drugs
• Indole Raw Materials is the intermediate of plant growth regulator indoleacetic acid and indolebutyric acid.

Indole powder can be widely used in jasmine, lilac, orange blossom, gardenia, lonicera, lotus, narcissus, ylang ylang, grass orchid, white orchid and other floral flavours, Indole Raw Materials is also often used with methyl indole to formulate artificial lingerie, and a very small amount of it can be used in the flavours of chocolate, hookah, strawberry, bitter orange, coffee, nuts, cheese, grapes and fruity compounds. Indole CAS 120-72-9

Indole CAS 120-72-9 is mainly used as raw materials for spices, dyes, amino acids and pesticides.Indole powder itself is also a kind of spice, which is often used in the formulation of daily-use flavours such as jasmine, lilac, lotus and orchid, and the dosage is generally in a few thousandths of a percent.

Tested for gold, potassium and nitrite to make jasmine-type flavours. Pharmaceutical industry.

Physicochemical Property of Indole powder

White shiny scale-like crystals, exposed to air and light turns dark. High concentration has a strong unpleasant odour, highly diluted (concentration <0.1%), was orange and jasmine like floral aroma.Indole Raw Materials Soluble in ethanol, ether, hot water, propylene glycol, petroleum ether and most non-volatile oils, insoluble in glycerol and mineral oil.

Production methodprocess of Indole powder

Catalytic dehydrogenation of o-aminoethylbenzene. In the presence of aluminium nitrate (or aluminium trioxide), o-aminoethylbenzene is dehydrocyclised at 550°C in a stream of nitrogen, and dihydroindole is obtained by distillation under reduced pressure. Then dehydrogenated at 640°C to obtain Indole Raw Materials .

1. Indole CAS 120-72-9 is obtained by reduction of 3-hydroxyindole, 3-hydroxy-2-hydroxyindole or indigo.
2. Indole powder is fractionated from the 220-260°C fraction of coal tar.
