Uses: Nitrogen Dioxide, NO2, has been used as a catalyst in certain oxidation reactions; as an inhibitor to prevent polymerization of acrylates during distillation; as a nitrating agent for organic compounds; as an oxidizing agent; as a rocket fuel; as a flour bleaching agent and in increasing the wet strength of paper.

Description: Nitrogen Dioxide is a reddish brown, toxic, paramagnetic gas at room temperature, the latter property being expected because it is a radical. NO2 condenses to a brown liquid, but freezes to a colorless solid.
