  • Applications

    1-Tetracosene (CAS 36731-16-5) is a long-chain terminal alkene (C24:1) with a double bond at carbon-1. In industrial contexts it is treated as a non-polar hydrocarbon and is commonly used in fragrance formulations as an odor carrier and fixative, and as a waxy constituent or thickener in cosmetics and personal care products. In coatings and printing, it can serve as a wax additive to improve the lubricity and gloss of the coating. Additionally, it is considered a chemical intermediate that can be converted into longer-chain hydrocarbons or functionalized derivatives for use as lubricants, plasticizers, or other specialty chemicals in industry.
