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.
Ball-and-stick model of diphenylmethane. The benzhydryl compounds are a group of organic compounds whose parent structures include diphenylmethane (which is two benzene rings connected by a single methane), with any number of attached substituents, including bridges.

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.

The nanometre is often used to express dimensions on an atomic scale: the diameter of a helium atom, for example, is about 0.06 nm, and that of a ribosome is about 20 nm. The nanometre is also commonly used to specify the wavelength of electromagnetic radiation near the visible part of the spectrum: visible light ranges from around 400 to 700 ...
In December 2023, the US Drug Enforcement Administration issued a notice of proposed rulemaking that would classify both 2,5-dimethoxy-4-iodoamphetamine and 2,5-dimethoxy-4-chloroamphetamine as schedule I controlled substances. [23] DOI is regularly used in animal and in vitro research. [24] Scheduling DOI could cause problems for medical ...
[2] [3] It can be viewed as benzaldehyde missing one hydrogen. The benzoyl group has a mass of 105 amu. The term "benzoyl" should not be confused with benzyl, which has the formula −CH 2 −C 6 H 5. The benzoyl group is given the symbol "Bz" whereas benzyl is commonly abbreviated "Bn".
