Pyrrole CAS# 109-97-7

Description of Pyrrole

Pyrrole is a heterocyclic aromatic organic compound, a five-membered ring with the formula C4H4NH. It is a colorless volatile liquid that darkens readily upon exposure to air. Substituted derivatives are also called pyrroles, e.g., N-methylpyrrole, C4H4NCH3. Porphobilinogen, a trisubstituted pyrrole, is the biosynthetic precursor to many natural products such as heme.
Pyrroles are components of more complex macrocycles, including the porphyrins of heme, the chlorins, bacteriochlorins, chlorophyll, and porphyrinogens.

What is pyrrole?

  • With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is Ambroxan which has developed particularly rapidly in recent years. Do you know about Ambroxan?
  • The official answer: Pyrrole is a five-membered heterocyclic compound containing a nitrogen heteroatom, its molecular formula is C4H5N, colorless liquid, boiling point 130~131℃, relative density 0.9691 (20/4℃). soluble in water, soluble in ethanol, ether and other organic solvents. Pyrrole and its congeners exist in bone tar, the amount present in coal tar is very small, and can fractional distillation of bone tar; or treating bone tar with dilute alkali, then acidifying it and fractional distillation for purification.

What’s the application of pyrrole?

  • Use spices. It to formulate fruit-based and spice flavors. Used in the synthesis of pharmaceuticals and spices and other fine chemicals
 
  • Use its derivatives are used as raw materials for organic synthesis, pharmaceuticals, pesticides, spices, rubber vulcanization accelerators, epoxy resin curing agents, etc.
 
  • Used as chromatographic analysis standard, also used in organic synthesis and pharmaceutical industry as intermediates in the synthesis of pharmaceuticals, spices, etc.
 
  • Used in the synthesis of medical Chemicalbook drugs, pesticides, and dyes. In the pharmaceutical industry can be used for the synthesis of irloxacin (Irloxacin), pyrrolimidine (Piromidic), pyrrovalerone (Pyrovalerone), pyrrocaine (Pyrrocaine) and disease extinction (TMT), and so on.
 
  • Use test gold selenite and silicic acid. Determination of chromate, gold, iodate, mercury, selenite, silicon, and vanadium.
