Safety Note: Phthalic Anhydride is harmful if swallowed and may cause skin irritation, serious eye damage, and allergic reactions following skin contact or inhalation. It may also cause allergy or asthma symptoms and breathing difficulties if inhaled. Avoid inhalation of dust and direct contact with the eyes and skin. Wear suitable personal protective equipment, including chemical-resistant gloves, safety goggles, and appropriate laboratory clothing. Handle in a well-ventilated area, preferably using a suitable chemical fume hood, and minimise dust generation. Store in a tightly closed container in a cool, dry, well-ventilated area, away from incompatible substances and moisture. Follow the supplier's Safety Data Sheet (SDS) for proper handling, storage, and disposal.
