DL-Lysine monohydrate(CAS: 885701-25-7)

DL-Lysine monohydrate (CAS: 885701-25-7) is a crystalline compound with a molecular weight of approximately 177.17 g/mol. It has a solubility of about 480 g/L in water at 25°C. Chemically, it is a monohydrate form of L-lysine, and it is less reactive than its anhydrous form. It is stable under normal conditions but may decompose at high temperatures or in strong acids.

DL-Lysine monohydrate (CAS: 885701-25-7) is typically synthesized by the fermentation of corn steep liquor or fermentation broth. The process involves microbial fermentation, followed by extraction, purification, and crystallization steps. Commonly used fermentation methods include fermentation of Corynebacterium glutamicum or Streptomyces natalensis. The yield can be around 90%, and the process often uses peptone as a nitrogen source and glucose as a carbon source.

DL-Lysine monohydrate (CAS: 885701-25-7) is widely used in the pharmaceutical industry for the production of feed additives and amino acid supplements. It is also used in the food industry as a flavor enhancer and nutritional supplement. Additionally, it has applications in the polymer industry for improving the stability and performance of certain polymers. Its use in sensors and semiconductors is more limited but is explored for specific applications requiring high purity.

When handling DL-Lysine monohydrate (CAS: 885701-25-7), it is important to wear appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. It should be stored in a cool, dry place away from direct sunlight and moisture. In case of a spill, use appropriate spill kits and ensure proper disposal. Always consult the Safety Data Sheet (SDS) for specific handling instructions and emergency procedures. It is not flammable but may decompose at high temperatures, so avoid heating or exposing to heat sources.
