Silver lactate is an organic chemical compound, a salt of silver and lactic acid[1] with the formula CH3CH(OH)COOAg.[2][3]

Synthesis

Silver lactate can be made by the reaction of silver carbonate with lactic acid.

Physical properties

Silver lactate forms light gray crystals.[4]

Silver lactate is soluble in water, slightly soluble in ethanol.

Silver lactate forms a crystalline hydrate of composition CH3CH(OH)COOAg•H2O.

Silver lactate is a reagent for the precipitation of uric acid.[5]

Chemical properties

The compound reacts with triphenylphosphine gold chloride in a mixed solvent of benzene and dichloromethane to obtain colorless triphenylphosphine gold lactate.[6]

The compound reacts with a tetraphosphine ligand, dppbpda, to obtain a coordination polymer [(dppbpda)Ag4(CH3CH(OH)COO)4]n.[7]
