Eutylone (also known as β-keto-1,3-benzodioxolyl-N-ethylbutanamine, bk-EBDB, and N-ethylbutylone) is a stimulant and empathogenic drug of the phenethylamine, amphetamine, phenylisobutylamine, and cathinone families which was developed in the 1960s, [3] [4] which is classified as a designer drug. [5]
Butylone can be synthesized in a laboratory via the following route: 3,4-methylenedioxybutyrophenone dissolved in dichloromethane to bromine gives 3′,4′-methylenedioxy-2-bromobutyrophenone. This product was then dissolved in dichloromethane and added to an aqueous solution of methylamine (40%). HCl was then added.
The halogenation of 2-Butyne-1,4-diol [110-65-6] (1) with chlorine gives Mucochloric acid [87-56-9] (2). Treatment with Phenylhydrazine [100-63-0] (3) gives 1-Phenyl-4,5-dichloro-6-pyridazone [1698-53-9] (4). Addition of ammonia leads to Chloridazon [1698-60-8] (5). Catalytic hydrogenation yields 5-amino-2-phenylpyridazin-3-one [13589-77-0] (6).
Butyric acid (butanoic acid) – histone deacetylase inhibitor and full agonist of free fatty acid receptor 2, free fatty acid receptor 3, and niacin receptor 1. Derivatives: butyrate (butanoate), sodium butyrate, methyl butyrate, ethyl butyrate, butyl butyrate, pentyl butyrate
2-Butyne (dimethylacetylene, crotonylene or but-2-yne) is an alkyne with chemical formula CH 3 C≡CCH 3. Produced artificially, it is a colorless, volatile, pungent liquid at standard temperature and pressure .
Butyne is an alkyne that contains 4 carbon and 6 hydrogen. It contains one triple bond and has two isomeric organic chemical compounds: 1-Butyne (ethylacetylene)

[7] [8] Chemical structure of acetylenedicarboxylate. Acetylenedicarboxylate (often abbreviated as ADC or adc) is a divalent anion with formula C 4 O 2− 4 or [O 2 C−C≡C−CO 2] 2−; or any salt or ester thereof. The anion can be derived from acetylenedicarboxylic acid by the loss of two protons.
