DICHLORACETIC ACID Chemical compatibility with O-rings, rubbers, & plastics

Dichloroacetic acid, also known as DCA or dichloroethanoic acid, is a colorless, pungent liquid with the chemical formula C2H2Cl2O2 used in the manufacture of pharmaceuticals, agrochemicals, and other specialty intermediates. This highly toxic organic acid can cause severe skin burns and respiratory irritation upon exposure. When assessing chemical compatibility, O-rings, rubber seals, gaskets, and plastic components must be carefully selected, as dichloroacetic acid can aggressively degrade certain rubber materials. Strict handling, storage, and protective protocols are essential for safety.
