They are weakly basic substances and can exist as either in a free base form or react with various acids to form salts such as amphetamine hydrochloride. The salt forms Adult wants sex tonight West union Illinois 62477 the amphetamines are highly water-soluble whereas the free base forms are less so Budavari, Amphetamines Amphetamines are structurally similar to dopamine and noradrenaline. They are a chiral molecule; that is, they can exist in two different chemical forms enantiomers that are identical in Online scrabble dating dimensions, but in three dimensions they are mirror images of each other.

A short history of amphetamine

A synthetic substance. Normally seen as a white powder, it acts as a stimulant of the central nervous system CNS. It is believed that amphetamine was first manufactured in the s by the German chemist Leuckart, Free local flirt evidence for this is lacking.

It appears that, as in the case of methamphetamine, systematic studies of its chemistry did not come about until the early twentieth century. Amphetamine has some limited therapeutic use, but most is manufactured in clandestine laboratories in Europe. It is under international control and closely related Free sex personals for Nantwich methamphetamine.

Amphetamine CAS is a member of the phenethylamine family, which includes a range of substances that may be stimulantsentactogens or hallucinogens.

It increases the activity of the noradrenaline and dopamine neurotransmitter systems. Amphetamine is less potent than methamphetaminebut in uncontrolled situations the effects are almost indistinguishable. The S -isomer has greater activity than the R -isomer.

It is rapidly absorbed after oral administration. After a single oral dose Backpage of charleston sc 10 mg, maximum plasma levels are around 0. The plasma half-life varies from 4 to 12 hours and is dependent on the urinary pH: alkaline urine decreases the rate of elimination.

A major metabolite is 1-phenylpropanone, with smaller amounts of 4-hydroxyamphetamine.

Fatalities directly attributed to amphetamine are rare. The estimated minimum lethal dose in non-addicted adults is mg. The most common route of synthesis is by the Leuckart method. This uses P2PBMK, phenylacetone and reagents Pocono country place houses for sale as formic acid, ammonium formate or formamide to yield a racemic mixture of the R- and S -enantiomers.

Effects of amphetamines

A Horny girls near 76148 less common, but stereoselective, method is by reduction of the appropriate diastereoisomers of norephedrine or norpseudoephedrine. Amphetamine may be ingested, snorted and, less commonly, injected.

Unlike the hydrochloride salt of methamphetamine, amphetamine sulfate is insufficiently volatile to be smoked. When ingested, a dose may vary from several tens to several hundreds of milligrams depending on the purity.

Other commonly used chemical names include 1-phenylaminopropane and phenyliospropylamine. Amphetamine is sometimes included with methamphetamine and other less common substances e. The Simon test produces a red coloration that will distinguish amphetamine a primary amine Plano massage therapist secondary amines such as methamphetamine blue coloration. Identification by gas chromatography—mass spectrometry can be improved by N -derivatisation, e. The R- and S -enantiomers levamfetamine and dexamfetamine respectively as well as the racemate a mixture of the R- and S -stereoisomers are listed in Schedule II of the United Nations Convention on Psychotropic Substances.
