Company Profile

In 2001, Watson Noke began its business with military intermediates used as additives in rocket, most of which are still our key products till today.

HNMR of  Triphenylbismuth and Tris(4-ethoxyphenyl)bismuthine

(Both are used as curing agent in rocket fuel)

Then, two original military intermediates were found to be used for other areas. From then on, Watson Noke started to serve customers in more fields and now has more than 100 competitive mature products along with thousands of intermediates during the development process.
