The vapor is heavier than air, so it can accumulate at low points. It is explosive at concentrations between 1.4 and 11.4%. [16] Concentrations in the air high enough to be flammable are intolerable to humans due to the irritating nature of the vapor. [12] Butanone fires should be extinguished with carbon dioxide, dry agents, or alcohol ...
4-Hydroxy-3-methoxyamphetamine (HMA), also known as 3-O-methyl-α-methyldopamine, is an active metabolite of 3,4-methylenedioxymethamphetamine (MDMA). [ 1 ] [ 2 ] [ 3 ] It is substantially less potent than MDMA or 3,4-methylenedioxyamphetamine (MDA) as a monoamine releasing agent in vitro .
4-Hydroxy-3-methoxymethamphetamine (HMMA) is an active metabolite of 3,4-methylenedioxymethamphetamine (MDMA). [ 1 ] [ 2 ] [ 3 ] It is a slightly more potent stimulant than MDMA in rodents. [ 4 ] The drug is substantially less potent than MDMA as a monoamine releasing agent in vitro .
3,4-Dihydroxymethamphetamine (HHMA, 3,4-DHMA), or 3,4-dihydroxy-N-methylamphetamine, also known as α-methylepinine or α,N-dimethyldopamine, is the major metabolite of 3,4-methylenedioxy-N-methylamphetamine (MDMA). [1] [2] [3] It is formed from MDMA by O-demethylation via cytochrome P450 enzymes including CYP2D6 as well as CYP1A2 and CYP3A4.
3-Methyl-2-pentanone (methyl sec-butyl ketone) is an aliphatic ketone and isomer of 2-hexanone. [2] References This page was last edited on 17 November 2024, at 23: ...
p-Cresol is a major component in pig odor. [11] Temporal glands secretion examination showed the presence of phenol and p-cresol during musth in male elephants. [12] [13] It is one of the very few compounds to attract the orchid bee Euglossa cyanura and has been used to capture and study the species.
3-Methyl-2-butanone (methyl isopropyl ketone, MIPK) is a ketone and solvent of minor importance. It is comparable to MEK ( Methyl ethyl ketone ), but has a lower solvency and is more expensive. [ 2 ]
It has the identical chemical formula with the methoxy group (−O−CH 3) that differs only in the attachment site and orientation to the rest of the molecule. However, their chemical properties are different. [1] [2] Hydroxymethyl is the side chain of encoded amino acid serine. [3]
