N-ALPHA-T-BUTOXYCARBONYL-N-DELTA-(2-CHLOROCARBOBENZOXY)-L-ORNITHINE - Introduction
N-tert-Butoxycarbonyl-N'-(2-chlorobenzyloxycarbonyl)-L-ornithine, abbreviated as CBZ-L-ornithine, is an organic compound. Its properties are as follows:
1. Appearance and properties: CBZ-L-ornithine is white or almost white crystalline powder.
2. melting point: about 175-180 degrees Celsius.
3. Solubility: CBZ-L-ornithine can be dissolved in common organic solvents, such as ethanol, methanol and dichloromethane.
The main use of CBZ-L-ornithine is as a protecting group in organic synthesis. It protects the α-amino group in the amino acid from being destroyed during the reaction. In the synthesis of peptides or proteins, CBZ-L-ornithine is often used to protect certain specific amino acids to control the selectivity and yield of the reaction.
The preparation of CBZ-L-ornithine usually starts from L-ornithine, which is first reacted with a tert-butoxycarbonyl compound to obtain N-tert-butoxycarbonyl-L-ornithine, and then reacted with 2-chlorobenzyl alcohol to form CBZ-L-ornithine.
Regarding safety information, CBZ-L-ornithine has not been specifically studied. However, as a chemical, operators should wear appropriate protective equipment, avoid contact with skin and eyes, and ensure that they are used in well-ventilated conditions. If ingested or inhaled, seek medical attention immediately.
