应用
It is used as a fertilizer, food additive, buffering agent, in molecular biology, biochemistry and chromatography. It is useful to increase the partition coefficients of amino acids in aqueous two-phase systems. It plays an important role for increase in rice grain yield by spraying chemicals including ferric chloride, di-potassium hydrogen phosphate and salicylic acid.
