Chemical and pharmaceutical intermediates are actually some chemical raw materials or chemical products used in the pharmaceutical synthesis process. For the synthesis of some drugs, the term pharmaceutical intermediate should be regarded as a general term for some chemical products, such as o-nitrobenzaldehyde, which is used for the anti-heart pain drug nitropyridine (heart pain drug) and reduces the nitro group to After the amino group becomes o-aminobenzaldehyde, quinoline ring drugs can be synthesized from it. This product is mainly used for pharmaceutical and dye intermediates, and a reagent for the detection of acetone.

Introduction of pharmaceutical intermediates

The domestic pharmaceutical intermediate industry has now entered a mature stage. The early days when a few skilled workers can build a factory and make profits have passed, and there will not be a situation similar to the production of more than a dozen drugs produced by a basic intermediate like oxetiaxamic acid. With the development of the pharmaceutical industry, there will be new demands for pharmaceutical intermediates, such as aztreonam-type intermediates, which will gradually increase in demand.

However, these new products have not yet formed a large market demand. At present, the pharmaceutical intermediates with relatively large domestic demand are still traditional products such as oxetiaxamic acid, norfoxamic acid and their derivatives. Enterprises that are new to the project should consider carefully, and reasonably grasp the timing of intervention on the premise that they have sufficient capital and technical strength and maintain a good relationship with pharmaceutical companies.
