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).
Over some time, tablet dimensions, weight, shape and concentration of LSD evolved from large (4.5–8.1 mm diameter), heavyweight (≥150 mg), round, high concentration (90–350 μg/tab) dosage units to small (2.0–3.5 mm diameter) lightweight (as low as 4.7 mg/tab), variously shaped, lower concentration (12–85 μg/tab, average range 30 ...

TPA-023 (MK-0777) is an anxiolytic drug with a novel chemical structure, which is used in scientific research. It has similar effects to benzodiazepine drugs, but is structurally distinct and so is classed as a nonbenzodiazepine anxiolytic.
Cenobamate was approved for medical use in the United States in November 2019, [3] [7] [8] [9] and placed in Schedule V of the Controlled Substances Act in March 2020. [10] Cenobamate was approved for medical use in the European Union in March 2021, [ 5 ] approved for use in the UK in December 2021, [ 11 ] and approved for use in Canada in June ...
