Mutagenicity of diisopropylamine dichloroacetate, the "active constituent" of vitamin B15 (pangamic acid).

Diisopropylamine dichloroacetate, the active component of many formulations of pangamic acid (trade-named "vitamin B15"), and diisopropylamine, a component of diisopropylamine dichloroacetate, both demonstrate mutagenicity in the Ames Salmonella/mammalian microsome mutagenicity test. Ninety percent of such agents prove carcinogenic, and this long-term possibility must be considered in any proposed use of pangamic acid containing diisopropylamine or diisopropylamine dichloroacetate.
