Mercury – named after a Roman god known for speed and agility – is a chemical element that has fascinated humans for thousands of years. Mercury is the only metallic element that is liquid under standard conditions. It flows easily and has very high surface tension, so it forms shiny rounded beads. When compared with most other metal elements, which are usually bits of greyish solids that tarnish quickly, it’s easy to see why mercury was thought to have special properties.

Mer­cury is a heavy, sil­very and very tox­ic met­al. One of the most well-known fea­tures of mer­cury is that in nor­mal con­di­tions this met­al is liq­uid and only freezes at –38.8°C! In na­ture there are only two el­e­ments that are liq­uid in nor­mal con­di­tions – mer­cury and bromine.In the earth’s crust, mer­cury is a very rare el­e­ment, but rocks in which mer­cury is found usu­al­ly con­tain it in rather high con­cen­tra­tions. This is be­cause mer­cury mix­es poor­ly with el­e­ments that make up most of the earth’s crust, and so “ac­cu­mu­la­tions” of min­er­als con­tain­ing mer­cury are formed. The most abun­dant of them are cinnabar (mer­cury sul­fide HgS) and corderoit (Hg₃S₂­Cl₂).

In the pharmaceutical industry, P2NP is used to produce a racemic amphetamine mixture, branded under the trade names Adderall and Mydayis, amongst others. In this case, the double bond is hydrogenated and the nitro group is reduced,[10] thus 1-phenyl-2-nitropropene becomes 1-phenyl-2-aminopropane, which is another name for amphetamine. Different reducing agents commonly lithium aluminium hydride (LAH), sodium borohydride,aluminum amalgam or Raney nickel are used in suitable solvents like isopropyl alcohol or tetrahydrofuran.

PMK ethyl glycidate as an intermediate in the synthesis of desoxy phenethylamine analogs. The desoxy phenethylamine analogs in this study represent a combination of alkyl side-chain and cyclic amines (azetidine, pyrrolidine, piperidine and azepane) to yield a set of mols. of identical elemental compn. as well as major mass spectral fragment ions (base peaks) of identical elemental compn.  These desoxy phenethylamine analogs of the aminoketone designer drug, 3,4-methylenedioxy-pyrrovalerone (MDPV) related to the natural product cathinone were prepd. from piperonal (3,4-methylenedioxybenzaldehyde) via the intermediate precursor ketones.  The aminoketones and the desoxy phenethylamine regioisomers were each sepd. in capillary gas chromatog. expts. using an Rxi-7Sil MS stationary phase with the aminoketones showing greater retention than the corresponding desoxyamines

Are pills stronger than ever, or just more dangerous? Does 'molly' actually contain any ecstasy? And what's a 'precursor'? This is what's happening with MDMA in 2015.It's 27 years since MDMA hit the front pages of British newspapers, and for a drug that's so widely consumed – only cannabis, alcohol and cocaine are more popular – it's still something of an enigma.In 2015, though, the story is not only mysterious, it's as complex as it is confusing and contradictory. As the MDMA market matures, it is splitting, with dirty, contaminated and downright deadly pills at one end of the scale, and dangerously high-dose tablets and unprecedentedly pure crystals at the other. Both these scenarios can pose risks and (let's be honest) offer enormous pleasure to users. In this feature, we've asked experts in the fields of chemistry, medicine, and clubbing to help you navigate the ever-changing landscape of ecstasy in 2015.
