PX-2 (also known as 5F-APP-PINACA, FU-PX and PPA(N)-2201) is an indazole-based synthetic cannabinoid that has been sold online as a designer drug. It contains a phenylalanine amino acid amide as part of its structure.
Sweden’s public health agency suggested classifying PX-2 as hazardous substance on November 10, 2014.
PX-2 is listed in the Fifth Schedule of the Misuse of Drugs Act (MDA) and therefore illegal in Singapore as of May 2015.
As of October 2015 PX-2 is a controlled substance in China.
