| Ethyl Tosylate Basic information |
| Ethyl Tosylate Chemical Properties |
| Ethyl Tosylate Usage And Synthesis |
Chemical Properties | Clear colorless to brownish liquid after melting | Uses | Ethyl p-toluenesulfonate can be used in the manufacture of organic synthesis, and also can be used as intermediate of methylation reagent and sensitive material. It also is flexibilizer of cellulose acetate. | Uses | For ethylation. | Uses | Ethyl p-toluenesulfonate was 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. | Synthesis Reference(s) | Chemical and Pharmaceutical Bulletin, 34, p. 2710, 1986 DOI: 10.1248/cpb.34.2710 The Journal of Organic Chemistry, 39, p. 3454, 1974 DOI: 10.1021/jo00937a050 | Safety Profile | Moderately toxic by
subcutaneous and intraperitoneal routes.
Questionable carcinogen with experimental
tumorigenic data. Mutation data reported.
Combustible when exposed to heat or
flame; can react with oxidzing materials. To
fight fire, use CO2, dry chemical. When
heated to decomposition it emits hlghly
toxic fumes of SOx. See also
