• Brand: Biosynth
• Description: 4-Formylbenzoic acid is an organic compound with the molecular formula CH2=C(O)CH=CHCO2H. It is a white solid that is soluble in water and has a strong, unpleasant odor. 4-Formylbenzoic acid has been shown to have affinity for binding to odorous molecules such as sulfur compounds, amines, and mercaptans. The binding of these molecules to the 4-formylbenzoic acid leads to a decrease in their odor concentration. This process can be done using electrochemical impedance spectroscopy or optical sensors. The oxidation of 4-formylbenzoic acid by trifluoroacetic acid produces 2-formylphenol and formaldehyde, which are themselves volatile compounds with an unpleasant odor. These reactions may be used as wastewater treatment methods. Langmuir adsorption isotherm may be used as an analytical method for measuring the concentration of 4-formylbenzoic acid
