Description
Potassium fluoride (KF, CAS 7789-23-3) is an inorganic salt supplied under trade names including Clocat F and known in French as fluorure de potassium. It carries no E-code designation and is classified under HS code 28261990. It is registered under REACH and holds EC number 232-151-5.
In pharmaceutical manufacturing, KF serves as a pH buffer and mild base catalyst in synthesis reactions, where its fluoride ion facilitates nucleophilic substitution. In electronics, it functions as a flux additive and surface treatment agent, promoting adhesion by etching oxide layers. Textile and leather processors apply it as an antimicrobial additive to inhibit microbial growth in process baths.
Potassium fluoride is available in spray-dried powder form, suitable for precise dosing in industrial processes. It is supplied in compliance with REACH regulations, with technical and pharmaceutical-grade options available depending on application requirements. Procurement teams should confirm grade specifications and packaging formats directly with our supply team.
