uses | 4-chloromethylbiphenyl is an important biphenyl derivative and has a wide range of uses in medicine, polymer liquid crystals, dyes, etc. For example, it can be used to synthesize non-steroidal anti-inflammatory drugs biphenylacetic acid, fenbufen, anti-inflammatory and analgesic diphenylacetate, etc. |
application | 4-chloromethylbiphenyl is an important biphenyl derivative, which is widely used in medicine, polymer liquid crystal, dyes, etc. Examples of its application are as follows: Preparation of 4-biphenylacetic acid. 4-biphenylacetic acid molecular formula C14H12O2, molecular weight 212.24, white flake crystal. 4-Biphenylacetic acid is a non-steroidal anti-inflammatory drug, an effective metabolite of fenbufen, and has anti-inflammatory and analgesic activity similar to fenbufen. Indications are variant arthritis, scapulohumeral periarthritis, tenosynovitis, tendinitis, muscle pain, traumatic swelling, pain, etc. Its derivative ethyl biphenylacetate is also an anti-inflammatory analgesic, which is used to treat rheumatoid arthritis, low back pain, frozen shoulder, traumatic pain, and postoperative pain. It has a good effect, especially for the treatment of cancer pain. The preparation method is: using 4-chloromethylbiphenyl as raw material, in the presence of catalyst palladium dichloride, ligand triphenylphosphine, base, solvent, and carbon monoxide after carbonylation reaction, and then acidification, Separation to obtain 4-biphenylacetic acid. The method can be realized under the conditions of reaction temperature of 50-100 ℃ and pressure of 0.3-1.0MPa, with high reaction yield and less discharge of three wastes, which is suitable for industrial production. |
