Description and Uses

Undecylenic acid (C11) or also called 10-undecenoic acid is an organic unsaturated fatty acid derived from castor oil by cracking. Undecylenic acid is an FDA approved active ingredient in medications for skin infections, and relieves itching, burning, and irritation. In technical applications it is used because if its antifungal properties.appearance (25°C) White or very pale yellow crystalline

Undecylenic acid can be used in silicon-based biosensors. Monolayers can be made on bare silicon transducer surfaces with the help of covalent bonds between silicon atom and the double bonds of undecylenic acid. The carboxylic acid groups remain available for the conjugation of biomolecules such as DNA or proteins.
