Catechol, 99%, Thermo Scientific Chemicals

Description

Catechol is used as a developer for photographic films, dyes and an intermediate for antioxidants in rubber and lubricating oils. It is used in polymerization inhibitors and in pharmaceuticals. It is a building block in organic synthesis and involved in the preparation of flavors and fragrances. It is used as a replacement for sandalwood oil, which is prepared from catechol through guaiacol and camphor. Further, it is a precursor for the preparation of vanillin from guaiacol, which is obtained by methylation reaction with catechol.

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.
