What is PMK glycidate?
PMK methyl glycidate is an analytical reference standard categorized as a precursor in the synthesis of methylenedioxy phenethylamines and amphetamines, including 3,4-MDMA . This product is intended for research and forensic applications.
PMK Glycidate product information:
Methyl 3-[3’4′-(methylenedioxy)phenyl]-2-methyl glycidate (MMDMG – also known as PMK-glycidate) was first detected in Australia in 2004 and is a non- controlled chemical made from piperonal, which is a precursor of 3,4-MDP-2-P.

General Synthesis of PMK
1. Formamide (65 g) and PMK (23 g) were refluxed at 190 *C for 5 h.
2. The solution was made basic and extracted with diethyl ether.
3. The ethereal solution was washed with dilute sulphuric acid, rinsed with water and finally dried over anhydrous sodium sulphate.
4. The diethyl ether volume was reduced to yield a clear yellow solution of N-formyl-3,4-methylenedioxyamphetamine (N-formylMDA).
5. This was added dropwise to LAH (2,5 g in 100 ml of sodium-dried diethyl ether) and refluxed for 3 h.
6. The excess LAH was decomposed by the addition of water and the resulting mixture was filtered, and the precipitate washed with diethyl ether.
7. The washings and the filtrate were combined and extracted with dilute sulphuric acid.
8. The aqueous solution was made alkaline with dilute sodium hydroxide and extracted with diethyl ether
9. The solvent was evaporated, leaving an amber oil of crude MDMA.
10. After the volume of the organic solvent was decreased, the remaining residue was treated with hydrogen chloride gas to yield a gelatinous brown precipitate of impure MDMA hydrochloride.
