Performance & Application

Specially used as a corrosion inhibitor for copper and copper

alloys in the semiconductor, microelectronics, display and printed

circuit board industries, it also has corrosion inhibition effect on

ferrous metals. By adsorption on the surface of copper to form a

thin film, so as to protect and control the etching and corrosion of

copper surface treatment process, but also can be used as a

pharmaceutical intermediate for the synthesis of cefteram piamyl

axel side chain.
