## Abstract The baseβcatalysed exchange of a proton of the methyl groups in acetanilides can be used to incorporate deuterium into these amides. 4β²βHydroxyβ2[^2^H]acetanilide (acetaminophen, paracetamol) can be prepared by the demethylation with boron tribromide of 4β²βmethoxyβ2[^2^H]acetamide obtai
The simultaneous use of the linear absorbances method and the derivative spectroscopy technique allows paracetamol to be spectrometrically determined in the presence of two interfering drugs that are generally associated with paracetamol in analgesic formulations. The proposed procedure does not nee
