## Abstract

The Drug Enforcement Administration is proposing to modify the listing of the list I chemical, N-phenylpiperidin-4-amine (also known as 4-anilinopiperidine; N-phenyl-4-piperidinamine; 4-AP) (hereinafter referred to as 4-anilinopiperidine), to include halides of 4- anilinopiperidine. The current listing of 4-anilinopiperidine includes its amides, its carbamates, and its salts, as list I chemicals under the Controlled Substances Act. The Drug Enforcement Administration proposes the new listing to read as follows: N-phenylpiperidin-4-amine (4-anilinopiperidine; N-phenyl-4-piperidinamine; 4-AP), its amides, its carbamates, its halides, its salts, and any combination thereof, whenever the existence of such is possible, as a list I chemical under the Controlled Substances Act.
