34317-61-8 - Introduction
S-Phenyl-L-cysteine (S-Phenyl-L-cysteine) is an unnatural amino acid consisting of a phenyl substituent attached to the backbone carbon of L-cysteine. The following is a description of the nature, use, manufacture and safety information of the S-Phenyl-L-cysteine:
Nature:
-Appearance: White crystal or crystalline powder
-Melting point: about 220-225°C
-Solubility: Slightly soluble in water and alcohol solvents
Use:
-Pharmaceutical field: S-Phenyl-L-cysteine can be used in the synthesis of antioxidants, cosmetics and biological key enzyme inhibitors and other drugs.
-Biochemical research: The compound can be used to study protein synthesis, metabolism and antioxidant reactions.
Preparation Method:
The preparation method of the S-Phenyl-L-cysteine can be obtained by the following steps:
1. The condensation of bromoacetophenone with thioacetate produces phenylethyl mercaptan.
2. Benzene ethanethiol reacts with aminopropanol to generate S-Phenyl-L-cysteine.
Safety Information:
There is limited safety data on S-Phenyl-L-cysteine, but no clear information on its toxicity or harmfulness has been reported. However, as with any chemical, appropriate laboratory procedures should be followed during use and appropriate personal protective measures should be taken, such as wearing gloves and laboratory glasses.
