p-Dioxane, Reagent, ACS
Introducing p-Dioxane, a high-purity reagent classified under the ACS (American Chemical Society) standards. This colorless liquid, known as a heterocyclic organic compound, possesses a light sweet odor reminiscent of diethyl ether and is categorized as an ether. As a miscible and hygroscopic substance, p-Dioxane plays a pivotal role in various chemical applications, particularly as a stabilizer for 1,1,1-trichloroethane during storage and transport in aluminum containers.
