Clear colorless to brownish liquid after melting
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.
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.

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
