[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.
2-Butyne is of interest to physical chemists because of its very low torsional barrier and the problem of determining that barrier using high-resolution infrared spectroscopy. Analysis of its spectrum [3] leads to a determination that the torsional barrier is only 6 cm −1 (1.2 × 10 −22 J or 72 J mol −1).
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.

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).
Butyne is an alkyne that contains 4 carbon and 6 hydrogen. It contains one triple bond and has two isomeric organic chemical compounds: It contains one triple bond and has two isomeric organic chemical compounds:
Its density at 25 °C and otherwise standard conditions is 0.766 g/ml. [1] The boiling point is 177 °C. [2] The average molar mass is 138.25 g/mol. 5-Decyne forms a group of symmetric alkynes with 4-octyne , 3-hexyne , and 2-butyne .
LGD-3303 is a drug which acts as a selective androgen receptor modulator (SARM), with good oral bioavailability. It is a selective agonist for the androgen receptor, producing functional selectivity with effective dissociation of anabolic and androgenic effects, acting as a partial agonist for androgenic effects, but a full agonist for anabolic effects.
