Mexacarbate is a carbamate pesticide developed by Alexander Shulgin and marketed in 1961 by Dow Chemical Company under the trade name Zectran. [1] As of 2009, mexacarbate is considered obsolete or discontinued, according to the World Health Organization. [2] It is notable for being the first biodegradable pesticide. [3]

<span class="mw-page-title-main">Alexander Shulgin</span> American biochemist and synthetic chemist, and recreational drug explorer

Alexander Theodore "Sasha" Shulgin was a Berkeley-trained American biochemist, broad researcher of synthetic psychoactive compounds, and author of works regarding these, who independently explored the organic chemistry and pharmacology of such agents—in his mid-life and later, many through preparation in his home laboratory, and testing on himself. He is acknowledged to have introduced to broader use, in the late 1970s, the prior synthesized compound, MDMA ("ecstasy") in research psychopharmacology and in combination with conventional therapy, the latter through presentations and academic publications, including to psychologists; and for the rediscovery, occasional discovery, and regular synthesis and personal use and distribution, possibly of hundreds of psychoactive compounds. As such, Shulgin is seen both as a pioneering and a controversial participant in the emergence of the broad use of psychedelics.

<span class="mw-page-title-main">2C-T-7</span> Psychedelic phenthylamine drug

2C-T-7 is a psychedelic phenethylamine of the 2C family. In his book PiHKAL: A Chemical Love Story, Alexander Shulgin lists the dosage range as 10–30 mg. 2C-T-7 is generally taken orally, and produces psychedelic and entactogenic effects that last 8 to 15 hours. Up until Operation Web Tryp and three deaths, two of which involved the use of other drugs in addition to 2C-T-7, and one which involved an excessive insufflated dose, 2C-T-7 was sold commercially in Dutch and Japanese smartshops and online. It is known on the streets as Blue Mystic or 7th Heaven. There has been little real research done on this chemical other than Shulgin's comments in PiHKAL and a few small animal studies mostly aimed at detecting metabolites.

It was first synthesized in 1970 by a team from the Texas Research Institute of Mental Sciences, and its activity was subsequently investigated in humans by Alexander Shulgin. In his book PiHKAL, Shulgin lists the dosage range as being from 20 to 60 mg. Lower doses of 10 mg or less have been explored for microdosing.

4-Acetoxy-DET (4-Acetoxy-N,N-diethyltryptamine), also known as ethacetin, ethylacybin or 4-AcO-DET, is a psychedelic tryptamine. It was first synthesized in 1958 by Albert Hofmann in the Sandoz lab.

<span class="mw-page-title-main">2C-O-4</span> Chemical compound

2C-O-4 (4-isopropoxy-2,5-dimethoxyphenethylamine) is a phenethylamine of the 2C family. It is also a positional isomer of isoproscaline and was probably first synthesized by Alexander Shulgin. It produces hallucinogenic, psychedelic, and entheogenic effects. Because of the low potency of 2C-O-4, and the inactivity of 2C-O, Shulgin felt that the 2C-O series would not be an exciting area for research, and did not pursue any further analogues.

<span class="mw-page-title-main">Endrin</span> Chemical compound

Endrin is an organochlorine compound with the chemical formula C12H8Cl6O that was first produced in 1950 by Shell and Velsicol Chemical Corporation. It was primarily used as an insecticide, as well as a rodenticide and piscicide. It is a colourless, odorless solid, although commercial samples are often off-white. Endrin was manufactured as an emulsifiable solution known commercially as Endrex. The compound became infamous as a persistent organic pollutant and for this reason it is banned in many countries.

<span class="mw-page-title-main">Globally Harmonized System of Classification and Labelling of Chemicals</span> International standard managed by the United Nations

The Globally Harmonized System of Classification and Labelling of Chemicals (GHS) is an internationally agreed-upon standard managed by the United Nations that was set up to replace the assortment of hazardous material classification and labelling schemes previously used around the world. Core elements of the GHS include standardized hazard testing criteria, universal warning pictograms, and safety data sheets which provide users of dangerous goods relevant information with consistent organization. The system acts as a complement to the UN numbered system of regulated hazardous material transport. Implementation is managed through the UN Secretariat. Although adoption has taken time, as of 2017, the system has been enacted to significant extents in most major countries of the world. This includes the European Union, which has implemented the United Nations' GHS into EU law as the CLP Regulation, and United States Occupational Safety and Health Administration standards.

2C (2C-x) is a general name for the family of psychedelic phenethylamines containing methoxy groups on the 2 and 5 positions of a benzene ring. Most of these compounds also carry lipophilic substituents at the 4 position, usually resulting in more potent and more metabolically stable and longer acting compounds. Most of the currently known 2C compounds were first synthesized by Alexander Shulgin in the 1970s and 1980s and published in his book PiHKAL. Shulgin also coined the term 2C, being an acronym for the 2 carbon atoms between the benzene ring and the amino group.

In 40 CFR 156.62, the EPA established four Toxicity Categories for acute hazards of pesticide products, with "Category I" being the highest toxicity category. Most human hazard, precautionary statements, and human personal protective equipment statements are based upon the Toxicity Category of the pesticide product as sold or distributed. In addition, toxicity categories may be used for regulatory purposes other than labeling, such as classification for restricted use and requirements for child-resistant packaging.
