Description

Indole CAS NO 120-72-9 is a heterocyclic aromatic organic compound, serving as a fundamental building block in organic synthesis and a key component in numerous natural products. Its unique bicyclic structure, consisting of a benzene ring fused to a pyrrole ring, makes it an essential intermediate for the production of pharmaceuticals, agrochemicals, and fragrances. This versatile compound is critical for manufacturers in the pharmaceutical, flavor & fragrance, and fine chemical industries seeking reliable, high-purity raw materials.

Application

• Pharmaceutical Intermediates: Core precursor for synthesizing tryptophan, serotonin, and various alkaloids, as well as active pharmaceutical ingredients (APIs) including anti-inflammatory and neurological drugs.
• Fragrance & Flavor Synthesis: Key component in the production of jasmine-like fragrances for perfumes, cosmetics, and detergents, and for creating specific flavor notes.
• Agrochemical Production: Used in the synthesis of certain plant growth regulators and advanced pesticide formulations.
• Dye and Pigment Manufacturing: Acts as a starting material for specific indole-based dyes and colorants.
• Research & Development: Essential reagent in academic and industrial R&D for organic chemistry, medicinal chemistry, and material science.
• Biochemical Studies: Used as a standard or probe in studies related to microbial signaling and plant physiology.
