China Key Intermediates Suppliers
Intermediate – Intermediate: A material produced during a drug substance processing step that must undergo further molecular modification or refinement to become a drug substance. Intermediates may or may not be isolated. Intermediates are the key products of the previous process of making APIs, which are different in structure from APIs.
for example:
Amoxicillin capsules are called preparations, amoxicillin is called API, and 6-APA is called intermediate.
Ceftriaxone sodium powder is called preparation, sterile ceftriaxone sodium is called API, and 7-ACA is called intermediate.
Our company specializes in providing Key Intermediates for various APIs
Intermediate is a very important type of fine chemical products. Its essence is a type of "semi-finished product", which is an intermediate product in the production of certain products. For example, if a product is to be produced, it can be produced from intermediates, saving costs and reducing It is widely used in the synthesis of medicines, pesticides, coatings, dyes and spices. In the field of medicine, intermediates are an important link in the industrial chain of the pharmaceutical industry. They are used for some chemical raw materials or chemical products in the process of drug synthesis. In a word, they are used to produce APIs.
