Product Technical Details

Product Overview

5,6-Difluoroindole-2-Carboxylic Acid is a specialized fluorinated heterocyclic compound engineered for high-performance applications in medicinal chemistry and organic synthesis. As a critical building block, this molecule features a unique indole core substituted with fluorine atoms at the 5 and 6 positions, alongside a carboxylic acid functional group at the 2 position. This specific structural arrangement enhances metabolic stability and bioavailability when incorporated into larger pharmaceutical scaffolds, making it an invaluable asset for drug discovery programs.

Our manufacturing process adheres to strict quality control protocols to ensure consistent batch-to-batch reliability. The introduction of fluorine atoms into the indole ring system significantly alters the electronic properties of the molecule, offering chemists superior handling characteristics during coupling reactions. This product is supplied as a tan powder with a guaranteed assay of not less than 97.0 percent, meeting the rigorous demands of industrial research and development laboratories.
