21CEC is specialized in supply high quality 99.5% Paclitaxel as Active Pharmaceutical Ingredients. 
With the guaranteed highest quality & lowest price. 

We select the best factories, inspecting and keep monitoring their real-time  production situation to ensure the high quality of 99.5% Paclitaxel that we provided. These factories have more than 8 years of Paclitaxel production experience. In associate with the universities / institutions, the quality of the product are analyzed by high-technology. There are large yew tree plant fields to ensure the sufficient material resource. The total production capability is >200kg/per year now. 

In additional, the 8 year clinical use of Paclitaxel Injection made by it and enormous research works proved its effectiveness and safety.

It needs 10 tons of yew tree leaves to extract and purify (natural extract by HPLC, no any semi-synthesis process)  1 kg 99.5% Paclitaxel. You can imaging the scale and skill implied during its production. Many sectors of  factories in different locations are involved in the whole process. 21CEC China Offices (Shanghai and Chengdu) have done excellent work on monitoring this production process.

Since we have pushed its quality improvement along the way, now the Paclitaxel that 21CEC provide is the highest quality & lowest price of its kind in the world.  No wonder more and more USA & Europe companies turned to our supply.

Manufacturing Procedure and Drug Master File (FDA):

There are several steps in the Paclitaxel extract & purification process;

(A) Extract from yew tree leaves and bark to obtain 1% Extract.
(B) Purify from 1% Extract to 50% Paclitaxel.
(C) Purification from 50% to 70% Paclitaxel.
(D) Further purification from 70% to 99.5% Paclitaxel.

The last step is the most high-tech one.

21CEC selected factories do have DMF files registered in FDA.
Based on our scientific strength and long term friendship with them, these factories trust 21CEC and provided us the content of DMF files in confidential. We appreciate this trust. Hence we be able to check all the manufacturing procedure and inspect the product quality accordingly.

This is the advantage of 21CEC for being one of the most reliable suppliers of high quality Paclitaxel in the world.
