A meso compound or meso isomer is an optically inactive isomer in a set of stereoisomers, at least two of which are optically active. [1] [2] This means that despite containing two or more stereocenters, the molecule is not chiral. A meso compound is superposable on its mirror image (not to be confused with superimposable, as any two objects ...
Of the three stereoisomers, two are enantiomers (levo- and dextro-2,3-butanediol) and one is a meso compound. [ 1 ] [ 2 ] The enantiomeric pair have (2 R , 3 R ) and (2 S , 3 S ) configurations at carbons 2 and 3, while the meso compound has configuration (2 R , 3 S ) or, equivalently, (2 S , 3 R ).
In biochemistry, medicine, and related sciences, inositol generally refers to myo-inositol (formerly meso-inositol), the most important stereoisomer of the chemical compound cyclohexane-1,2,3,4,5,6-hexol. Its formula is C 6 H 12 O 6; the molecule has a ring of six carbon atoms, each with an hydrogen atom and a hydroxyl group (–OH).
In chemistry, isomers are molecules or polyatomic ions with identical molecular formula – that is, the same number of atoms of each element – but distinct arrangements of atoms in space. [1] Isomerism refers to the existence or possibility of isomers. Isomers do not necessarily share similar chemical or physical properties.
meso-Stilbene dibromide is an organic compound with a formula of (C 6 H 5 CH(Br)) 2. [3] It is one of three isomeric stilbene dibromides, the others being the pair of enantiomers . All are white solids.

One modern-day method of chiral resolution is used in the organic synthesis of the drug duloxetine: [4] RRR synthesis. In one of its steps the racemic alcohol 1 is dissolved in a mixture of toluene and methanol to which solution is added optically active (S)-mandelic acid 3. The alcohol (S)-enantiomer forms an insoluble diastereomeric salt with ...
In chemistry, metamerism is used to define the isomeric relationship between compounds with the same polyvalent, heteroatomic, functional group but differ in the main carbon chain or any of the side chains. It has rather been an obsolete term for isomerism, which has not been recognised by IUPAC in its publications. [1]
