27825-21-4 - Introduction
Methyl is a chemical compound with the chemical formula C7H5ClN2O2. The following is a description of the properties, uses, preparation and safety information of the compound:
Nature:
Methyl L is a white crystalline powder. It is stable at room temperature, but soluble in some organic solvents, such as ethanol and dichloromethane. It can be structurally characterized by techniques such as GC-MS or NMR.
Use:
Methyl L has certain uses in the field of organic synthesis. It can be used in the synthesis of Pyrazine compounds, such as precursors of drugs and pesticides. In addition, it can also be used as intermediates and reagents in pharmaceutical research.
Method:
Methyl L can be prepared by the reaction of pyrazine and Chloroacetyl Chloride. The specific synthetic steps include reaction of pyrazine and Chloroacetyl Chloride under alkaline conditions, followed by acid treatment and alkaline hydrolysis to obtain the product, and finally crystallization purification.
Safety Information:
Appropriate laboratory safety measures, such as wearing protective gloves, goggles and protective clothing, should be taken when handling Methyl. It may decompose at high temperatures and produce harmful gases. In addition, it should avoid contact with skin, eyes and respiratory tract, avoid ingestion and inhalation, and avoid contact with strong oxidants. In case of exposure or inhalation, emergency measures should be taken immediately and medical assistance should be sought. During storage, it should be kept in a dry, well-ventilated place.
