Usage

General Description

4-Methylindole-3-carboxaldehyde, also known as skatole, is an organic compound known for its strong odor. It is naturally produced from the breakdown of tryptophan in the digestive tract of mammals and is a major contributor to fecal smell. This yellowish-white crystalline compound finds applications in the perfume industry, where it is utilized to create earthy, jasmine-like scents. It may occur in small quantities in essential oils such as jasmine and orange blossom. Despite its unpleasant smell in high concentrations, in extremely dilute solutions, its odor can be pleasant.
