  • COMPOSITIONS COMPRISING DICHLOROACETIC ACID, PROCESSES FOR PREPARING SAME AND USES THEREOF
    Publication number: 20240158432
    Abstract: A composition comprising dichloroacetic acid and glyoxylic acid, wherein, the content of glyoxylic acid is below 1000 pm, and the preparation method and application of the composition. A process for preparing the composition, comprising: mixing a dichloroacetic acid material having greater than 1000 ppm glyoxylic acid with a glyoxylic acid capture reagent, and a process for preparing oligonucleotides, comprising using the composition. It is found that glyoxylic acid is an impurity in commercially available DCA products, which may cause the oligonucleotides synthesis failure. Ion chromatography can be used to detect glyoxylic acid in dichloroacetic acid and accurately determine its concentration.
