Description and Uses
4-Hydroxypyridine, available from pyridylpyridinium chloride hydrochloride, is the substrate for diodone and its n-propyl ester, propyliodone. 4-Hydroxypyridine (4-HP) is a non-nucleophilic analog of the product phenol found to bind specifically to and stabilize the aminoacrylate intermediate. When 4-HP is added to Tyrosine phenol-lyase (TPL) reactions, an absorption peak at 340 nm is observed. The formation of the 340 nm peak correlates with the decay of the quinonoid intermediate peak at 505 nm, with a clean isosbestic point, and the observed rate constants show an inverse dependence on the concentration of 4-HP. These results confirm that the observed peak at 340 nm is due to the formation of the amino acrylate intermediate[1-2].
4-Hydroxypyridine was used in the synthesis of (Ag3MoO3F3) (Ag3MoO4)Cl by hydro(solvato)thermal methods. It was used as model compound to study the natural photodegradation of representative aquatic environmental contaminants.
