Pharmaceutical intermediates are actually some chemical raw materials or products used in the process of drug synthesis. This chemical product does not require a production license for drugs and can be produced in ordinary chemical plants. As long as it reaches a certain level, it can be used for drug synthesis. Pharmaceutical intermediates can be divided into major categories according to their application fields, such as antibiotic drug intermediates, antipyretic and analgesic drug intermediates, cardiovascular system drug intermediates, anti-cancer drug intermediates, etc.

After more than 30 years of steady development in China's pharmaceutical intermediate industry, the chemical raw materials and intermediates required for pharmaceutical production can basically be matched, and only a small number of complex synthetic intermediates need to be imported to meet the demand. Moreover, due to China's abundant resources and low raw material prices, many intermediates have been exported in large quantities.

There is a gap between China's pharmaceutical intermediates and the world level, due to the fact that China's intermediate drugs mainly rely on imitation, often with low-level repetition and lack of innovation. Up to now, China has independent intellectual property rights for intermediate drugs in the worldrarelyPharmaceutical intermediate products are generally high value-added fine chemical products, and developing this series of products is the main way for enterprises to seek new economic growth points.

In recent years, significant achievements have been made in the application of roll up nanofiltration membrane technology in the medical field. Due to its ability to effectively remove high valence ions, pigments, and salts, roll up nanofiltration membranes can greatly reduce osmotic pressure and increase the water production of each component.

Compared with traditional technology, nanofiltration technology:

1. The system adopts nanofiltration operation mode, which can concentrate the desalinated solution 25 times, achieving a dual effect of desalination and concentration, increasing the content of effective substances, and reducing the production load for subsequent treatment sections. If the substances contained in the permeate have certain economic value, they can be recovered, increasing the economic benefits of the enterprise.

During the operation of the nanofiltration membrane separation equipment, there is no phase change, the degree of automation control is high, and no other chemical agents are added to achieve clean production, reducing environmental pollution; The equipment has a small footprint, simple process, low investment, and low operating costs.

The yield of effective substances can be improved to a certain extent, and the recovery of effective components in the permeate can reach over 98%.

Literide can customize cost-effective process packages according to user needs, conduct comprehensive analysis and reasonable design of membrane separation equipment, and effectively control various process links such as design, manufacturing, and production of membrane separation equipment to achieve the dual combination of economic performance and technical advantages of the entire process package, thereby providing customers with both professional and comprehensive process package design.
