MPHP also known as 4′-Methyl-α-pyrrolidinohexiophenone is a stimulant chemical compound that is closely related to Pyrovalerone. The chemical formula for MPHP is C17H25NO. The average mass is 259.386505 Da and the monoisotopic mass is 259.193604 Da. The Systematic name for MPHP is 1-(4-Methylphenyl)-2-(1-pyrrolidinyl)-1-hexanone.

Research on MPHP was conducted by ACD/Labs’, US Environmental Protection Agency’s EPISuite, and ChemAxon. Properties that were predicted by ACD/Labs showed 2 #H bond acceptors, 6 #Freely rotating bonds, index of refraction at 1.531 with a surface tension of 39.015998840332 dyne/cm, a flash point of 131.388 ºC and a boiling point of 377.004 ºC at 760 mmHg.

Properties that were predicted by the US Environmental Protection Agency’s EPISuite showed the boiling point at 350.83, melting point at 117.24, and the vapor pressure estimations at 1.54E-005. The report also showed water solubility at 25 deg C (mg/L): 12.67. The removal in wastewater treatment was 76.06 percent for total removal, total biodegradation is 0.67 percent, total sludge adsorption is 75.39 percent, and to air 0.00.

Properties that were predicted by ChemAxon included a topology analysis, which showed an atom count of 44, bond count of 45, cyclomatic number of 2, chain atom count of 8, chain bond count of 9, asymmetric atom count of 1, and rotatable bond count of 6. Under geometry, the information provided showed deriding energy of 53.04 kcal/mol with a volume of 272.78 Å3, a minimal projection area of 54.71 Å2 and maximum at 79.80 Å2.

Chemical and physical properties of MPHP include a heavy atom count of 19, topological polar surface area of 20.3, covalently bonded unit count of 1, feature 3D acceptor count of 1, feature 3D cation count of 1, feature 3D hydrophobe count of 1, feature 3D ring count of 2, and effective rotor count of 7.

MPHP is only intended for research purposes in a controlled laboratory for forensic or scientific study and is NOT intended for human consumption.
