Sigma Aldrich Formic acid puriss. p.a., ACS reagent, reag. Ph. Eur., ≥98%
Formic acid is a simple organic acid. Formate group (-COOH) plays an important role to compose the complex biomolecules (acetic acid, glycine, various amino acids). It exhibits high polarity and its dipole moment is 1.41Debye. It has been reported as a substiute for fuel in polymer electrolyte membrane (PEM) fuel cells. Its permeation through Nafion ™ 112 and 117 membranes has been compared with that of methanol.
