2-Methylsuccinic Acid CAS 498-21-5

1. 2-Methylsuccinic acid serves as an attractive monomer or synthon for synthesizing polymers like biodegradable polyesters (e.g., poly(butylene succinate-co-butylene 2-methylsuccinate)), which have applications in coatings, cosmetic solvents, and bioplastics .
2. 2-Methylsuccinic acid CAS 498-21-5 is used as a flux material, an important dyestuff intermediate, and an intermediate in pharmaceutical synthesis .
3. As a normal metabolite found in human fluids, 2-Methylsuccinic acid is also a key intermediate in fatty acid breakdown .

1. Store 2-Methylsuccinic acid in a tightly sealed container in a cool, dry, and well-ventilated place, as it is stable under normal temperatures but incompatible with bases, oxidizing agents, and reducing agents .
2. Keep 2-Methylsuccinic acid CAS 498-21-5 away from strong oxidizing agents, strong reducing agents, and strong bases to prevent hazardous reactions .
3. Handle 2-Methylsuccinic acid using appropriate personal protective equipment including chemical-resistant gloves and safety goggles; avoid dust formation, and contact with skin, eyes, and clothing .

1. Isolate the spill area, wear personal protective equipment, and avoid dust generation; sweep up or vacuum spilled 2-Methylsuccinic acid and place it into a suitable, sealed, labeled container for disposal .
2. Prevent 2-Methylsuccinic acid CAS 498-21-5 from entering drains or waterways, as it may be harmful to the environment .
3. Personnel cleaning 2-Methylsuccinic acid spills should use water spray, dry chemical, carbon dioxide, or chemical foam for fire suppression if needed .

1. 2-Methylsuccinic acid is classified with GHS signal word "Warning" and causes skin irritation (H315), serious eye irritation (H319), and may cause respiratory irritation (H335) .
2. 2-Methylsuccinic acid CAS 498-21-5 is harmful if swallowed, inhaled, or absorbed through the skin ; thermal decomposition or combustion produces toxic fumes including carbon monoxide and carbon dioxide .
3. 2-Methylsuccinic acid has a flash point of 111°C, is combustible, and is not classified as dangerous goods for transport .
