HOT-x
HOT-x, also known as 4-alkylthio-2,5-dimethoxy-N-hydroxyphenethylamines or hydroxylated 2C-T derivatives, are a group of psychedelic drugs of the phenethylamine and 2C families. They have a hydroxy group at the amine as well as methoxy groups at the 2 and 5 positions and an alkylthio group at the 4 position of the phenyl ring. The HOT-x drugs are the N-hydroxyl analogues of the corresponding 2C-T-x drugs.
The HOT-x drugs were synthesized and tested by Alexander Shulgin and were reported by him in his 1991 book PiHKAL.
