Applications

Pyrrole plays a major role in synthesis of drugs, spices, agrochemicals, dyes, photographic chemicals and perfumes. It plays an important role in the electropolymerisation of macroporous conducting polymer films. It acts as a catalyst for polymerization process; as a standard substance in chromatographic analysis; as corrosion inhibitors and preservatives and as solvents for resins and terpenes. It is utilized to study the hydrogen-bond mediated coupling of 1,2,3-triazole to pyrrole and in the preparation of 1-(4-Chloro-benzoyl)-pyrrole by reacting with 4-Chloro-benzoyl chloride. In Ciamician-Dennstedt rearrangement, It is used to prepare 3-chloropyridine by reacting with dichlorocarbene.
