5-Chloro-2-methoxybenzaldehyde - Introduction
It is an organic compound with a molecular formula of C8H7ClO2 and a molecular weight of 170.59g/mol. Its physical properties include a white crystalline solid with a melting point of 58-61°C and a boiling point of 277-280°C. The compound is soluble in non-polar solvents such as diethyl ether, chloroform and dichloromethane at normal temperature, and hardly soluble in water.
It can be used as an intermediate in organic synthesis in the laboratory. It is often used in the preparation of biologically active molecules and drugs, such as anti-tumor drugs, hormones and enzyme inhibitors. Such compounds can also be used in the synthesis of novel organic photosensitive materials and dyes.
The preparation method can be by reacting benzaldehyde and thionyl chloride, then adding methanol and performing reductive deoxygenation. The specific steps include reacting benzaldehyde and thionyl chloride in an appropriate solvent to obtain a thionyl chloride adduct, then adding methanol and a reducing agent (such as hydrogen or sodium sulfite) for deoxygenation, and finally purifying by crystallization to obtain the target product.
When using and handling, pay attention to the following safety information. This compound is irritating and can cause irritation of the eyes, skin and respiratory tract, so necessary protective measures should be taken, such as wearing protective glasses, gloves and masks. Avoid breathing its vapor or contact with its solution. When handling the compound, do it in a well-ventilated area and avoid contact with flammable materials. Storage should be sealed, away from fire and oxidant. In case of accidental contact or inhalation, seek medical attention immediately.
