Use

Pyrrole is a five-membered heterocyclic compound which contains one nitrogen atom, it is colorless liquid at room temperature, naturally presents in coal tar and bone oil, turns black color quickly in the air, it has significant irritant odor. The main type use is the preparation of fruit and spice flavors. It is used for the synthesis of pharmaceuticals and fine chemicals such as perfume. Its derivatives are widely used in organic synthesis, pharmaceuticals, pesticides, spices, rubber vulcanization accelerator, epoxy curing agents of raw materials. Also it is widely used in the synthesis of pharmaceuticals, pesticides and dyes. In the pharmaceutical industry can be used for synthesis of Barossa Star (Irloxacin), meters pyrrole acid (Piromidic), pyrrole pentanone (Pyrovalerone), pyrrole Cain (Pyrrocaine) and set off disease (TMT) and the like.
