(S)-2-tert-Butoxycarbonylamino-3-mercapto-propionic acid - Introduction
Boc-L-cysteine is a compound whose chemical name is t-butoxycarbonyl-L-cysteine. According to its name, it is known that it contains a cysteine group in its structure, and a BOC protecting group is attached to this group.
Boc-L-cysteine is a white crystalline solid. Its molecular formula is C11H19NO5S and its molecular weight is 289.34. The compound has a melting point of 85-87°C. It is less soluble in water, but more soluble in organic solvents such as dimethyl sulfoxide (DMSO) and acetonitrile.
The main use of Boc-L-cysteine is as an unnatural amino acid in organic synthesis. It can be used as a protecting group for cystine to synthesize polypeptides or proteins with specific biological activities. In addition, the compound can also be used in the field of drug development, such as the synthesis of compounds with antioxidant, anti-tumor or anti-infective activity.
The methods for preparing Boc-L-cysteine are relatively diversified. Common methods include the reaction of amine acid and (2S)-dimethyl -2-thiopropanol catalyzed by trypsin, or the synthesis of amino acid peptide chains, cysteine is thus obtained. Next, the amino group in the cysteine was protected using a BOC protecting group to obtain a Boc-L-cysteine.
Regarding safety information, Boc-L-cysteine are chemicals, and safety measures need to be paid attention to during operation. It may cause irritation to the skin, eyes and respiratory system. Wear protective gloves, goggles and masks during operation. In addition, it should also be operated in a well-ventilated place to avoid inhalation or contact with its dust or solution. In case of contact with skin or eyes, rinse immediately with plenty of water and seek medical help. Follow the correct use and handling practices of laboratory and chemicals to ensure safe operation.
