The so-called pharmaceutical intermediates are actually some chemical raw materials or chemical products used in the process of drug synthesis. This kind of chemical product can be produced in an ordinary chemical factory without the production license of the medicine. As long as it reaches some level, it can be used for the synthesis of medicines.
In China, more than 2,000 raw materials and intermediates are needed for chemical industry each year, and the demand is more than 2.5 million tons. After more than 30 years of development, the chemical raw materials and intermediates required for pharmaceutical production in China can basically be matched, and only a small part needs to be imported. Moreover, due to the abundant resources in China and the low prices of raw materials, many intermediates have achieved a large number of exports.
