  • Applications

    Ethyl Nitrate (CAS number: 625-58-1) is a nitrate ester primarily used as an energetic material in blasting and propellant formulations; it also serves as a reactive intermediate in organic synthesis for access to nitrate-ester derivatives and related energetic compounds; in specialized laboratory settings it may be used as a solvent or reaction medium under tightly controlled conditions for nitration-related chemistry; as a building block in certain synthesis routes for energetic materials, it is handled under strict safety and regulatory controls.
