N-Formylmescaline

N-Formylmescaline, also known as N-formyl-3,4,5-trimethoxyphenethylamine, is an alkaloid and possible psychedelic drug of the phenethylamine and scaline families related to mescaline. It is the N-formyl derivative of mescaline. N,''N-Diformylmescaline has been found to be chemically unstable under acidic or basic conditions, breaking down into N''-formylmescaline, which then further degrades into mescaline. Relatedly, it is thought that N-formylmescaline and N,''N-diformylmescaline may act as prodrugs of mescaline in vivo. N''-Formylmescaline is known to occur naturally in trace amounts in peyote. It is not a controlled substance in Canada as of 2025.
