Some of these chemicals come with inhibitors added (e.g. BHT) to help prevent peroxide formation, but formation can still occur over time. Commonly used peroxide formers include diethyl ether, tetrahydrofuran (THF), and cyclohexene.
WebPeroxide Formers are chemicals that can form shock sensitive explosive peroxides over time. Many organic solvents commonly used in labs are peroxide formers. Typical … Webpre-label peroxide-forming chemicals (e.g. diethyl ether, tetrahydorfuran) with an expiration date.
