Alpha-Terpinene >94% is a monoterpene hydrocarbon found naturally in plants, widely used in fragrances, flavors, and as a solvent in chemical synthesis. It contributes citrusy, pine-like aromas and exhibits antioxidant properties, making it valuable in cosmetics, pharmaceuticals, and cleaning products. In agriculture it is also formulated into terpenoid-based foliar insecticide blends for field crops and serves as an inert ingredient in non-food pesticide products. This chemical has a CAS number of 99-86-5, a molecular formula of C10H16, and a molecular weight of 136.23 g/mol. It must be stored at -15 to -20°C and carries a Danger signal word because it may be fatal if swallowed and enters the airways (aspiration hazard). It is also a flammable liquid, harmful if swallowed, may cause an allergic skin reaction and causes serious eye irritation. Molekula supplies alpha-Terpinene >94% from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
