(3,4-Dimethoxyphenyl)(phenyl)methanone(CAS: 4038-14-6)

(3,4-Dimethoxyphenyl)(phenyl)methanone is a white crystalline solid with a molecular weight of approximately 260.24 g/mol. It has a low solubility in water (0.04 g/100 mL at 25°C) and good solubility in organic solvents such as methanol, ethanol, and dichloromethane. This compound is relatively stable but can react with strong acids or bases. It is not flammable and has a melting point around 128-130°C. For storage and handling, it is recommended to keep in a cool, dry place away from direct sunlight.

(3,4-Dimethoxyphenyl)(phenyl)methanone can be synthesized through a condensation reaction between 3,4-dimethoxyphenylacetic acid and phenylmagnesium bromide in an anhydrous solvent like THF. The reaction typically requires a Lewis acid catalyst, such as boron trifluoride etherate, to enhance the reactivity. The yield is usually around 70-80% with good selectivity towards the desired product. This synthesis is performed under inert conditions to avoid oxidation or deprotection of the sensitive methoxy groups.

(3,4-Dimethoxyphenyl)(phenyl)methanone is used in various industries, particularly in the pharmaceutical and polymer sectors. In the pharmaceutical industry, it serves as a key intermediate in the synthesis of certain drugs. In polymer manufacturing, it can be used as a monomer or additive to enhance properties like flexibility and thermal stability. Additionally, it has applications in the production of sensors and semiconductors given its electronic properties.

When handling (3,4-Dimethoxyphenyl)(phenyl)methanone, it is important to wear appropriate personal protective equipment (PPE) including gloves, goggles, and a lab coat. This compound should be stored in a cool, dry place away from direct sunlight and flammable materials. Spills should be cleaned up using absorbent materials and disposed of according to local regulations. Always refer to the Safety Data Sheet (SDS) for detailed handling and emergency procedures. The compound is non-toxic by oral ingestion but may cause skin irritation; immediate medical attention should be sought if exposure occurs.
