"In today's market, it is not enough simply to offer a large base of technologies; the focus must be on the willingness to provide innovation and integration within those chemistries and offer solutions to customer problems."

Customer Synthesis
We'd like to provide customer synthesis to our clients based on our own products and/or technical strengths due to guaranteed quality and delivery time. We can provide you the most derivatives of our own products. We are skilled at: asymmetric hydrogenation, Grinard reaction, Birth reduction, phosgenation, azidation etc. However, we are open-minded to any other kind of synthesis problems, and we will give you our confirmation within 24 h.
Complimentary Sourcing Service
Unless you authorize us to do a complete survey, all preliminary sourcing services, such as searching product availability, checking company background, or referring a customer synthesis manufacturer in China etc. is free of charge to our customers.
We have a broad network in fine chemical industry in China. As psychologist Stanley Milgram said in a concept of " six degrees of separation", which refers to the fact that there's a chain of no more than six people that links every people on this planet to every other person. When comes to Chinese fine chemical community, rarely will we ever need to use all six links. In most cases, we can get to a prospect in China with just one or two contacts.
