3, 5-dihydroxypentyl benzene is an important pharmaceutical intermediate in the pharmaceutical industry. In the past, it could be obtained by degrading lichens and extracting lichenic acid, but the yield of 3, 5-dihydroxypentyl benzene was low. Some scientists found that 3, 5-dihydroxypentyl benzene has a good inhibiting effect on human immune system diseases, so it was quickly applied widely in the medical industry.
It is known that 3, 5-dihydroxypentyl benzene has a variety of biological activities, and can be used in combination with some anti-immune drugs to alleviate human immunodeficiency and other diseases, and achieve good effects.
The demand for 3, 5-dihydroxypentyl benzene is increasing in the domestic and foreign pharmaceutical markets, and more and more preparation methods are available. By improving the technology, yield, utilization rate and cost, the scale production can be achieved and the pollution to the environment can be avoided or reduced.
