China Special Intermediates Suppliers

Our Special Intermediates are mainly a combination of our own actual product structure and product properties, including: 1. The product does not belong to any other product of our company intermediates, 2. Chemical reaction type is more special 3. Can be used to synthesize two or more kinds of API which roles is almost equivalent and difficult to separate the level. 4. This intermediate is somewhat less used for actual production or less practical use. We summarized the above four cases of intermediates temporarily as a special intermediate, if the special intermediate application is enlarge, we will adjust it according to the actual situation to change its "identity."
