Lutropur® MSA
Lutropur® MSA
Lutropur MSA is pure methanesulfonic acid. Methanesulfonic acid (MSA) is a strong and odorless organic acid with a unique property profile that distinguishes it from all other acids. Benefits in practical applications come from its nonoxidizing nature, the high solubility of its salts, the absence of color and odor, and the fact that it is readily biodegradable. MSA is becoming increasingly important in a number of applications and industries, including as a replacement for acid catalysts in esterification reactions. It is finding increasing use in polyurethane prepolymers as a stabilizer to displace other conventional options like benzoyl chloride (now a “red listed raw material”) & phosphoric acid.
