2-(N-cyclohexylamino)ethanesulfonic+acid: PubChem CID. 66898; UNII: 71X53V3RZ1 ... CHES (N-cyclohexyl-2-aminoethanesulfonic acid) is a buffering agent. CHES buffers ...
HEPES (4-(2-hydroxyethyl)-1-piperazineethanesulfonic acid) is a zwitterionic sulfonic acid buffering agent.It is one of the twenty Good's buffers.HEPES is widely used in cell culture, largely because it is better at maintaining physiological pH despite changes in carbon dioxide concentration (produced by aerobic respiration) when compared to bicarbonate buffers, which are also commonly used in ...
Cyclohexylamine is an organic compound, belonging to the aliphatic amine class. It is a colorless liquid, although, like many amines, samples are often colored due to contaminants.
The mechanism of the Michaelis–Arbuzov reaction. The Michaelis–Arbuzov reaction is initiated with the S N 2 attack of the nucleophilic phosphorus species (1 - A phosphite) with the electrophilic alkyl halide (2) to give a phosphonium salt as an intermediate (3). These intermediates are occasionally stable enough to be isolated, such as for ...
Ethanesulfonic acid (esylic acid) is a sulfonic acid with the chemical formula CH 3 CH 2 SO 3 H. The conjugate base is known as ethanesulfonate or, when used in pharmaceutical formulations, as esilate. It is a colorless liquid. [2]
Sodium 2-hydroxyethyl sulfonate (also: sodium isethionate) is the sodium salt of 2-hydroxyethane sulfonic acid (isethionic acid), it is used as a hydrophilic head group in washing-active surfactants, known as isethionates (acyloxyethanesulfonates) due to its strong polarity and resistance to multivalent ions.

The reaction mechanism for the Johnson–Corey–Chaykovsky reaction consists of nucleophilic addition of the ylide to the carbonyl or imine group. A negative charge is transferred to the heteroatom and because the sulfonium cation is a good leaving group it gets expelled forming the ring.
