Abstract
Abstract N,N-dimethylformamide dimethyl acetal, a methylating reagent, has been used on artificial corticosteroid dexamethasone to improve its GC-MS responsiveness. The major reaction product gave unexpected low resolution mass spectra. Its structure has been unambiguously determined. This compound, a corticosteroid ester usually obtained after numerous reaction steps1, could be of great interest in the fields of analytical chemistry and drug residues survey.
