Amendment to 3,4-MDP-2-P Methyl Glycidic Acid, a List I Chemical

Document 2026-15624 is a Proposed Rule published by the Department of Justice in the Federal Register on August 3, 2026. The Drug Enforcement Administration is proposing to modify the listing of the list I chemical 3,4-MDP-2-P methyl glycidic acid (also known as PMK glycidic acid) to include esters of 3,4-MDP-2-P methyl glycidic acid, not listed elsewhere in the Controlled Substances Act (CSA), as list I chemicals under the CSA. The current listing of 3,4- MDP-2-P methyl glycidic acid includes its salts, optical and geometric isomers, and salts of isomers. DEA proposes the new listing to read as follows: 3,4-MDP-2-P methyl glycidic acid (PMK glycidic acid) and its esters, not listed elsewhere in the CSA, its optical and geometric isomers, its salts, salts of its optical and geometric isomers, salts of its esters, not listed elsewhere in the CSA, and any combination thereof, whenever the existence of such is possible.
