Application
1. It can be used in the manufacture of organic synthesis, and also can be used as intermediate of ethylation reagent and sensitive material. It also is flexibilizer of cellulose acetate.
2. It is used to develop an extraction method for methyl and ethyl esters of various sulfonic acids in active pharmaceutical ingredients using solid-phase micro extraction coupled to GC/MS in the selected ion monitoring mode. It was used in a study to develop a fast and accurate method for determination of residues of some common alkylating agents employed in drug synthesis by in situ derivatization-headspace-gas chromatography-mass spectrometry.
