23 hours ago · Chemistry Modern synthesis of ibuprofen. Ibuprofen is practically insoluble in water, but very soluble in most organic solvents like ethanol (66.18 g/100 mL at 40 °C for 90% EtOH), methanol, acetone and dichloromethane. The original synthesis of ibuprofen by the Boots Group started with the compound isobutylbenzene. The synthesis took six steps.

23 hours ago · LSD is a chiral compound with two stereocenters at the carbon atoms C-5 and C-8, so that theoretically four different optical isomers of LSD could exist. LSD, also called (+)-d-LSD, has the absolute configuration (5R,8R). 5S stereoisomers of lysergamides do not exist in nature and are not formed during the synthesis from d-lysergic acid.
