is a five membered heterocyclic compound containing a nitrogen heteroatom. Its molecular formula is C4H5N, a colorless liquid. Slightly soluble in water, easily soluble in ethanol, ether and other organic solvents. Pyrrole becomes black under the action of trace oxygen; The loose tablet reaction gives red color; Polymerize into pyrrole red under the action of hydrochloric acid; It is generally unstable to oxidants. Pyrrole and its homologues mainly exist in bone tar, and the amount of coal tar is small, which can be obtained by fractionation of bone tar; Or the bone tar is treated with dilute alkali, and then acidified and fractionated for purification. Its derivatives are widely used as raw materials for organic synthesis, medicine, pesticide, spice, rubber vulcanization accelerator, epoxy resin curing agent, etc. It is used as a reference material for chromatographic analysis, as well as in organic synthesis and pharmaceutical industry.
