Sodium formate-d is the deuterium labeled Sodium formate.Sodium formate is a biochemical assay reagent. Sodium formate can react with zinc sources (such as ZnCl2) on the surface of alpha alumina support to form a zinc oxide layer. Sodium formate acts as a deprotonating agent, promoting the deprotonation of ligands (such as 2-methylimidazole) at high temperatures. Sodium formate provides the required reducing force in the catalytic oxidation of methane to methanol by methane monooxygenase (sMMO) and inhibits further oxidation of methanol[1][2].
