3, 5-Dihydroxypentyl benzene is an important pharmaceutical intermediate. In the early years, it was degraded and extracted by lichen plants to obtain lichen acid. However, the yield of 3, 5-dihydroxypentyl benzene was relatively low. Scientists have found that 3,5-dihydroxypentyl benzene has a good inhibiting effect on human immune system diseases, so it has been quickly and widely used.
It is known that 3,5-dihydroxypentyl benzene has a variety of biological activities and can be used to alleviate human immunodeficiency and other diseases in combination with anti-immune drugs.
The demand for 3,5-dihydroxypentyl benzene is increasing in the pharmaceutical market, and there are more and more preparation methods. Through scientific and reasonable preparation process, the technology, yield, utilization rate and cost have been improved. At the same time, it is necessary to reduce the unfriendly pollution to the environment.
