·Large-scale Reduction


We have experience in large-scale reaction up to tons. The mature manufacturing technique, new-type reaction equipment and competitive price are all in advantage.

·Large-scale Grignard Reaction


We have two R&D groups that have specialized in boric acid product synthesis for more than 20 years and have accumulated rich experience from lab-scale trials to scale-up. With a fully equipped plant, new product development and process optimization can be achieved in a short time.

·Large scale brominationreaction


We weeded out the traditional technology which used a diazotization process from amino pyridine to bromide pyridine, instead, we attach bromine directly onto the pyridine ring, to achieve the purpose of high yield and low cost.

By using this technology, we developed aseries of similar products, such as:

3-Pyridyl bromide       CAS: 626-55-1

3,5-Dibromo-4-methylpyridine       CAS:3430-23-7

5-Bromo-2-picoline       CAS: 3430-13-5

3-Bromo-2-methylpyridine       CAS: 38749-79-0

3-Bromo-4-methylpyridine       CAS: 3430-22-6

·Large scale couplingreaction


With more than 15 years experience on coupling reaction, we are capable of using suitable catalyst to increase the yield and reduce the cost.
