About Indoles and Indole-sulfur Compounds

Indole is a compound of pyrrole and benzene in parallel, also known as benzopyrrole, with the chemical formula C8H7N. There are two combinations of pyrrole and benzene, called indole and isoindole, respectively.

Indole and its homologues and derivatives are widely found in nature. They are a large class of compounds with benzo-five-membered nitrogen heterocyclic structure units. They are mainly found in natural flower oils, such as jasmine, bitter orange, daffodil, and vanilla Waiting.

Indole compounds are an important class of heterocyclic derivative alkaloids, which show a variety of biological activities in the organism.

MS-based technical means can realize the qualitative and quantitative analysis of indoles and indole-sulfur compounds.

Application Field

  • In the field of medicine, indole compounds can be used to synthesize antipyretic analgesics, stimulants, antihypertensive drugs, vasodilators, and anti-resistive amines.
  • In the field of pesticides, indole compounds are widely used in high-efficiency plant growth regulators, fungicides, etc. For example, indole acetic acid and indole-3-butyric acid are important plant regulators.
  • In the field of perfume production, indole and 3-methylindole have a beautiful floral taste after being diluted, and are often used in the blending of artificial flower essential oils such as jasmine, lemon, lilac, orchid, and lotus. Generally, the indole used in perfume is the extract of coal tar instead of chemical synthesis, and the amount is very small.
  • In the dye industry, many downstream products derived from indole can be used as raw materials for dye synthesis, and can produce azo dyes, phthalic dyes, cationic dyes and indole methane dyes, as well as a variety of new functional dyes.
