The Edgewood Arsenal code name for 3,4-DMA was EA-1316. [1] Note that two other positional isomers of dimethoxyamphetamine, 2,6-DMA and 3,5-DMA, have also been made, but these drugs have not been tested in humans and their effects are unknown.
2,5-DMA is a low-potency serotonin 5-HT 2A receptor partial agonist, with an affinity (K i) of 2,502 nM, an EC 50 Tooltip half-maximal effective concentration of 160 to 2,352 nM (depending on the signaling cascade), and an E max Tooltip maximal efficacy of 66%. [3] It has also been assessed at several other receptors. [3]
3.08568 cm – 1 attoparsec; 3.4 cm – length of a quail egg [112] 3.5 cm – width of film commonly used in motion pictures and still photography; 3.78 cm – amount of distance the Moon moves away from Earth each year [113] 4.3 cm – minimum diameter of a golf ball [114] 5 cm – usual diameter of a chicken egg
DMA was first reported in 1850 by the German chemist A. W. Hofmann, who prepared it by heating aniline and iodomethane: [3] [4] C 6 H 5 NH 2 + 2 CH 3 I → C 6 H 5 N(CH 3) 2 + 2 HI. DMA is produced industrially by alkylation of aniline with methanol in the presence of an acid catalyst: [5] C 6 H 5 NH 2 + 2 CH 3 OH → C 6 H 5 N(CH 3) 2 + 2 H 2 O

Moving average crossover of a 15-day exponential close-price MA (red) crossing over a 50-day exponential close-price MA (yellow) In the statistics of time series, and in particular the stock market technical analysis, a moving-average crossover occurs when, on plotting two moving averages each based on different degrees of smoothing, the traces of these moving averages cross.
In genetics, a centimorgan (abbreviated cM) or map unit (m.u.) is a unit for measuring genetic linkage. It is defined as the distance between chromosome positions (also termed loci or markers ) for which the expected average number of intervening chromosomal crossovers in a single generation is 0.01.
[251]: 50 [273] Thereafter, in the late 1980s, the drug spread alongside rave culture to the UK and then to other European and American cities. [251]: 50 Illicit MDMA use became increasingly widespread among young adults in universities and later, in high schools. Since the mid-1990s, MDMA has become the most widely used amphetamine-type drug ...
