Benzamide is an organic compound with the chemical formula of C 7 H 7 NO. It is the simplest amide derivative of benzoic acid . In powdered form, it appears as a white solid, while in crystalline form, it appears as colourless crystals. [ 5 ]
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.
Benzamidine is a reversible competitive inhibitor of trypsin, trypsin-like enzymes, and serine proteases. [4]It is often used as a ligand in protein crystallography to prevent proteases from degrading a protein of interest.
A mass spectrum is a histogram plot of intensity vs. mass-to-charge ratio (m/z) in a chemical sample, [1] usually acquired using an instrument called a mass spectrometer. Not all mass spectra of a given substance are the same; for example, some mass spectrometers break the analyte molecules into fragments ; others observe the intact molecular ...
Benzaldehyde oxime undergoes Beckmann rearrangement to form benzamide, catalyzed by nickel salts [3] or photocatalyzed by BODIPY. [4] Its dehydration yields benzonitrile.It can be hydrolyzed to regenerate benzaldehyde.
When both temperature and pressure are held constant, and the number of particles is expressed in moles, the chemical potential is the partial molar Gibbs free energy. [ 1 ] [ 2 ] At chemical equilibrium or in phase equilibrium , the total sum of the product of chemical potentials and stoichiometric coefficients is zero, as the free energy is ...
The benzoyl functional group.. In organic chemistry, benzoyl (/ ˈ b ɛ n z oʊ ɪ l /, BENZ-oh-il) [1] is the functional group with the formula −COC 6 H 5 and structure −C(=O)−C 6 H 5. [2] [3] It can be viewed as benzaldehyde missing one hydrogen.
Benzimidazole is a base: . C 6 H 4 N(NH)CH + H + → [C 6 H 4 (NH) 2 CH] +. It can also be deprotonated with stronger bases: . C 6 H 4 N(NH)CH + LiH → Li [C 6 H 4 N 2 CH] + H 2. The imine can be alkylated and also serves as a ligand in coordination chemistry.
