Hazard Symbols Xi - Irritant Risk Codes 43 - May cause sensitization by skin contact Safety Description S36/37 - Wear suitable protective clothing and gloves. S24/25 - Avoid contact with skin and eyes. S22 - Do not breathe dust. WGK Germany 3 RTECS RC6308000 TSCA Yes HS Code 2922491990L-Norleucine (H-Nle-OH) (CAS: 327-57-1), is an isomer of leucine. A non-proteinogenic L-alpha-amino acid comprising hexanoic acid carrying an amino group at C-2. It does not occur naturally. As a non-essential amino acid, L-Norleucine can be used as internal standard in amino acid analysis. Unusual amino acids, used in peptide synthesis, organic synthesis intermediates, pharmaceutical intermediates, biochemical reagents, chemical reagents. Overview: Unnatural amino acids are the core intermediates of many drugs, especially new drugs in the past 10 years. The production processes of unnatural amino acids such as L-n-leucine mainly include asymmetric synthesis, chemical resolution and biological enzyme catalysis. Among them, asymmetric synthesis is not widely used in industrial production due to the relatively expensive chiral catalysts and chiral auxiliary reagents; chemical resolution is gradually not in line with the current requirements of clean production due to the large consumption of raw materials, large pollution, and low chiral content; bioenzyme catalysis has the advantages of high stereoselectivity, mild reaction conditions, high chiral content, product serialization, and less pollution. It is the development direction of non-natural amino acid industrial production technology in the future.
