The structure of a general cyanohydrin. In organic chemistry, a cyanohydrin or hydroxynitrile is a functional group found in organic compounds in which a cyano and a hydroxy group are attached to the same carbon atom. The general formula is R 2 C(OH)CN, where R is H, alkyl, or aryl.
In organic chemistry, a cyanohydrin reaction is an organic reaction in which an aldehyde (−CH=O) or ketone (>C=O) reacts with a cyanide anion ...

Acetone cyanohydrin (ACH) is an organic compound used in the production of methyl methacrylate, the monomer of the transparent plastic polymethyl methacrylate (PMMA), also known as acrylic. It liberates hydrogen cyanide easily, so it is used as a source of such.
Chloral cyanohydrin is the cyanohydrin derivative of chloral (trichloroacetaldehyde). It was historically used as a source of hydrogen cyanide for medicinal purposes. [ 1 ] Chloral cyanohydrin is toxic by inhalation.
The cyanohydrin itself is derived from a separate aldehyde. The reactants of the oxazole synthesis itself, the cyanohydrin of an aldehyde and the other aldehyde itself, are usually present in equimolar amounts. [3] Both reactants usually have an aromatic group, which appear at specific positions on the resulting heterocycle. Fischer Oxazole ...
The Kiliani–Fischer synthesis, named for German chemists Heinrich Kiliani and Emil Fischer, is a method for synthesizing monosaccharides.It proceeds via synthesis and hydrolysis of a cyanohydrin, followed by reduction of the intermediate acid to the aldehyde, thus elongating the carbon chain of an aldose by one carbon atom while preserving stereochemistry on all the previously present chiral ...
Acetone cyanohydrin has been determined to be the natural substrate of HbHNL, though HbHNL also shows activity with mandelonitrile, the natural substrate of PaHNL.The cleavage of mandelonitrile into benzaldehyde and cyanide is what produces the characteristic amaretto smell of almonds. [18]
