General structure of 25-NB derivatives, where R is usually 2,5-dimethoxy-4-(alkyl or halogen), R 1 is usually H but rarely methyl, and Cyc is usually 2-substituted phenyl but can be other heterocycles.
Benzonitrile is a useful solvent and a versatile precursor to many derivatives. It reacts with amines to afford N-substituted benzamides after hydrolysis. [3] It is a precursor to diphenylmethanimine via reaction with phenylmagnesium bromide followed by methanolysis.

In semiconductor manufacturing, the 2 nm process is the next MOSFET (metal–oxide–semiconductor field-effect transistor) die shrink after the 3 nm process node.. The term "2 nanometer", or alternatively "20 angstrom" (a term used by Intel), has no relation to any actual physical feature (such as gate length, metal pitch or gate pitch) of the transistors.

Dimethylbutadiene, formally referred to as 2,3-dimethyl-1,3-butadiene, is an organic compound with the formula (CH 3) 2 C 4 H 4. It is colorless liquid which served an important role in the early history of synthetic rubber .
The tendency of the 4-cyano substitution to confer high 5-HT 2A selectivity had previously been observed with DOCN, [29] but this was not sufficiently potent to be widely adopted as a research ligand. 25CN-NBOH is still slightly less selective for 5-HT 2A than the more complex cyclised derivative 2S,6S-DMBMPP ((2S,6S)-2-(2,5-dimethoxy-4-bromobenzyl)-6-(2-methoxyphenyl)piperidine), [30] in ...
