21124-40-3 - Introduction
Α-(2-thienyl)glycine is an amino acid derivative with the chemical formula C6H7NO2S. The following is a description of its nature, use, preparation and safety information:
Nature:
α-(2-thienyl)glycine is a white crystal or crystalline powder, soluble in water and alcohol solvents. It is a chiral molecule, there are two stereoisomers, α-(2-thienyl)glycine is a mixture.
Use:
α-(2-thienyl)glycine is an important intermediate in organic synthesis, which is used in the preparation of drugs, dyes and pesticides. It can also be used in the synthesis of polypeptide and protein components of drugs.
Method:
The preparation of α-(2-thienyl)glycine is generally obtained by reacting thiophen-2-ol with bromoacetic acid. The thiophen-2-ol is first reacted with sodium bisulfite to give the thiophene-2-mercapto compound. The thiophene-2-mercapto compound is then reacted with bromoacetic acid under basic conditions to give α-(2-thienyl)glycine.
Safety Information:
There is limited information on the safety of α-(2-thienyl)glycine. This compound is organic and should be handled, stored and used in accordance with standard laboratory safety practices, including wearing suitable protective gloves, glasses and protective clothing. In addition, the relevant substance safety data form should be read carefully before handling, and its contact with strong oxidants or flammable substances should be avoided. If you need to know more about its safety, please consult the relevant professional institutions or the safety guidance in the actual operation of the laboratory.
