DL-Norleucine CAS 616-06-8

1. DL-Norleucine is a non-proteinogenic amino acid used primarily as a research tool and pharmaceutical intermediate for synthesizing various biologically active compounds .
2. DL-Norleucine CAS 616-06-8 can satisfy the methionine requirement for cephalosporin C production in chemically defined media, stimulating antibiotic biosynthesis .
3. DL-Norleucine is employed in protein engineering studies as a methionine analog, where incorporation into proteins like adenylate kinase can confer enhanced resistance to oxidative inactivation .

1. Store DL-Norleucine in a tightly sealed container in a cool, dry, well-ventilated place, protected from light and direct sunlight .
2. Keep DL-Norleucine CAS 616-06-8 powder at -20°C for up to 3 years stability; for solutions, store at -80°C for 6 months or -20°C for 1 month in tightly sealed vials .
3. Handle DL-Norleucine using appropriate personal protective equipment including safety goggles and gloves, as standard hygiene practices should be followed when handling research chemicals .

1. Isolate the spill area, wear full protective equipment including suitable respirator, and avoid dust generation when handling solid DL-Norleucine .
2. Sweep up spilled DL-Norleucine CAS 616-06-8 using non-sparking tools into sealed, labeled containers for disposal; for solutions, absorb with inert material like diatomite .
3. Prevent DL-Norleucine from entering drains or waterways, and dispose of waste according to local, state, and federal environmental regulations .
