On April 2, 2021, Zhang, Zhihu; Tang, Zheng; Wang, Hao; Gao, Sen; Cui, Chaohui published a patent.HPLC of Formula: 121129-31-5 The title of the patent was Preparation of 3,3-dimethyl-2-oxobutanoic acid and its sodium salt. And the patent contained the following:

The invention relates to preparation of sodium 3,3-dimethyl-2-oxobutanoate and its sodium salt, which has the advantages of environmental friendliness and stability. The 3,3-dimethyl-2-oxobutyric acid and sodium salt thereof were prepared by the following steps: oxidation of sodium 2-hydroxy-3,3-dimethylbutanoate and sodium chlorite to obtain sodium 3,3-dimethyl-2-oxobutanoate; (2) acidification sodium 3,3-dimethyl-2-oxobutanoate to obtain free acid. The experimental process involved the reaction of Methyl 2-hydroxy-3,3-dimethylbutanoate(cas: 121129-31-5).HPLC of Formula: 121129-31-5
