Description

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.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
