4-Formyl-6-methoxy-3-nitrophenoxyacetic acid is a photolabile formylated nitrophenol that is used to study the formation of concentration gradients across cell membranes. 4-Formyl-6-methoxy-3-nitrophenoxyacetic acid has been found to react with proton gradients and formyl groups in the membrane, which produces formaldehyde. The reaction mechanism for this process is not well understood, but it has been proposed that the reaction proceeds through a transducing step in which an electron from the formyl group reacts with a proton gradient to produce a formate ion. This mechanism is supported by experiments that show that the rate of photochemical reactions increases as the pH gradient across the membrane decreases.

2-(2-Nitrophenoxy)acetic acid (NPAA) is a molecule that has been found in plants of the genus Balanites. It has been shown to be an intramolecular hydrogen bond acceptor, which may contribute to its chemical structure and stability. NPAA has also been shown to have a constant pKa value of 4.7, which means it is slightly acidic. NPAA is used as an industrial process sample preparation agent and can be synthesized by reacting phenol with nitric acid.
