Application

Formic acid solution can be used to study biological buffers and buffer solutions. Formic acid solution has been used in a study to develop a sensitive and easy analytical method for catecholamine metabolites including 4-hydroxy-3-methoxyphenylglycol sulfate (HMPG sulfate), vanillylmandelic acid (VMA) and homovanillic acid (HVA) determination. Formic acid solution has also been used in a study to develop a method for the determination of the eight quinolones of veterinary use regulated by the European Union.
