2,5-Dimethoxy-4-ethylamphetamine (DOET, DOE, Hecate) is a psychedelic drug of the phenethylamine and amphetamine chemical classes. It was first synthesized by Alexander Shulgin , and was described in his book PiHKAL ( Phenethylamines i Have Known And Loved ).
Dihydrotachysterol (DHT) is a synthetic vitamin D analog activated in the liver that does not require renal hydroxylation like vitamin D 2 (ergocalciferol) and vitamin D 3 (cholecalciferol). DHT has a rapid onset of action (2 hours), a shorter half-life, and a greater effect on mineralization of bone salts than does vitamin D. [ 1 ]
2,4-Dimethylpentane is an alkane with the chemical formula [(H 3 C) 2 CH] 2 CH 2. This colorless hydrocarbon is produced in large quantities in oil refineries. It results from the alkylation of isobutane by propylene. [1] Often referred to as "alkylate", it is blended with other gasoline components to give a high octane fuel.
Heptene is a higher olefin, or alkene with the formula C 7 H 14. The commercial product is a liquid that is a mixture of isomers . It is used as an additive in lubricants, as a catalyst , and as a surfactant .
Triazabicyclodecene (1,5,7-triazabicyclo[4.4.0]dec-5-ene or TBD) is an organic compound consisting of a bicyclic guanidine. For a charge-neutral compound, it is a relatively strong base that is effective for a variety of organic transformations. TBD is colorless solid that is soluble in a variety of solvents. [4]

Brassicasterol (24-methyl cholest-5,22-dien-3β-ol) is a 28-carbon sterol synthesised by several unicellular algae (phytoplankton) and some terrestrial plants, like rape.This compound has frequently been used as a biomarker for the presence of (marine) algal matter in the environment, and is one of the ingredients in stigmasterol-rich plant sterols (Number E499 in the European numbering system).
It can be prepared by base-catalyzed isomerization of 2,3-dimethyl-1-butene. [2] Another route involves direct dimerization of propylene. [3] It can also be produced by photolysis of tetramethylcyclobutane-1,3-dione. [4]
