L-Methionine CAS 63-68-3

1. L-Methionine is an essential amino acid crucial for protein synthesis, serving as a fundamental nutritional supplement in cell culture, food products, and animal feed to promote growth and health .
2. L-Methionine CAS 63-68-3 acts as a precursor for important compounds, including the antioxidant glutathione, supporting liver health and detoxification processes, and is studied for its anti-aging properties .
3. L-Methionine functions as a chelating agent for heavy metals like lead and mercury, and is utilized in research on metabolic pathways and protein engineering .

1. Store L-Methionine in a tightly sealed container in a cool, dry place at room temperature (RT) or refrigerated, protected from light and strong oxidizing agents .
2. Keep L-Methionine CAS 63-68-3 under an inert atmosphere for long-term stability, as L-Methionine may react with strong oxidizers and is incompatible with strong acids and alkalis .
3. Handle L-Methionine using appropriate personal protective equipment including gloves and safety goggles, and avoid breathing dust by working in a well-ventilated area or fume hood .

1. Isolate the spill area, wear suitable protective equipment including dust mask, and sweep up solid L-Methionine into sealed, labeled containers without creating dust .
2. Dampen spilled L-Methionine CAS 63-68-3 with water and transfer to a suitable container, then wash contaminated surfaces with soap and water; prevent L-Methionine from entering drains or waterways .
3. Personnel cleaning L-Methionine spills must dispose of waste according to environmental regulations, as L-Methionine is readily biodegradable and not expected to bioaccumulate .

1. L-Methionine is generally recognized as non-hazardous with low acute toxicity (LD50 oral rat: 36,000 mg/kg), but may cause eye, skin, and respiratory tract irritation upon dust exposure .
2. L-Methionine CAS 63-68-3 is combustible and when heated to decomposition emits toxic fumes including nitrogen oxides, sulfur oxides, and carbon oxides; violent reactions possible with strong oxidizing agents .
3. L-Methionine is not classified as dangerous goods for transport, has a melting point of 284°C (dec.), and is soluble in water with a pH of 5-7 (10 g/l at 20°C) .
