Safety and Storage
Succinyl Chloride reacts vigorously with water and moisture, releasing corrosive hydrogen chloride gas. It is essential to handle this product under dry, inert conditions using appropriate personal protective equipment and fume hood facilities. Store in tightly sealed, corrosion-resistant containers under inert atmosphere in a cool, dry, well-ventilated area away from heat and ignition sources.
