甲基麦冬黄烷酮 B - Introduction
Methylophiopogonanone B is an organic compound with the chemical formula C15H16O2. The following is a description of the nature, use, formulation and safety information of methyllophiopogonanone B:
Nature:
Methylophiopogonanone B is a colorless to slightly yellow solid with a special odor. It is soluble in many organic solvents such as ethanol, benzene and ether at room temperature, but insoluble in water.
Use:
Methylophiopogonanone B is commonly used as an important intermediate in organic synthesis. It can play a key role in the synthesis of certain organic compounds, such as certain hormones, drugs and pesticides.
Preparation Method:
Methylophiopogonanone B has many preparation methods. One of the common methods is to synthesize it by reacting Ophiopogonanone flavonoids with anhydrous methanol under alkaline conditions. After the reaction is completed, the pure product is purified by distillation and crystallization.
Safety Information:
Methylophiopogonanone B is relatively stable under general conditions, but it may burn when encountering flammable substances such as high temperature and open flame. It is irritating to the skin and eyes and needs to be avoided. Wear protective glasses, gloves and protective clothing during operation to ensure good ventilation. In addition, it should be stored in a dry, ventilated and cool place to avoid contact with oxidants and acids. If taken by mistake or inhaled by mistake, please seek hospital treatment immediately.
