Pentanal (also called valeraldehyde) is the organic compound with molecular formula C 4 H 9 CHO. Classified as an alkyl aldehyde , it is a colorless volatile liquid. Its odor is described as fermented, bready, fruity, nutty, berry.
This unsaturated aldehyde is then partially hydrogenated to form 2-ethylhexanal, a precursor to plasticizers such as bis(2-ethylhexyl) phthalate. [ 4 ] Butyraldehyde is a component in the two-step synthesis of trimethylolpropane , which is used for the production of alkyd resins .

Synthetic routes for the production of isovaleraldehyde vary. One method is by the hydroformylation of isobutene: (CH 3) 2 C=CH 2 + H 2 + CO → (CH 3) 2 CH−CH 2 CHO. A small amount of 2,2-dimethylpropanal ((CH 3) 2 C(CHO)CH 3) side product is also generated.
Aldehyde structure. In organic chemistry, an aldehyde (/ ˈ æ l d ɪ h aɪ d /) is an organic compound containing a functional group with the structure R−CH=O. [1] The functional group itself (without the "R" side chain) can be referred to as an aldehyde but can also be classified as a formyl group. Aldehydes are a common motif in many ...
It is an aldehyde, isomeric with n-butyraldehyde (butanal). [1] Isobutyraldehyde is made, often as a side-product, by the hydroformylation of propene. Its odour is described as that of wet cereal or straw. It undergoes the Cannizzaro reaction even though it has alpha hydrogen atom. It is a colorless volatile liquid.
The oxidation of primary alcohols to carboxylic acids normally proceeds via the corresponding aldehyde, which is transformed via an aldehyde hydrate (gem-diol, R-CH(OH) 2) by reaction with water. Thus, the oxidation of a primary alcohol at the aldehyde level without further oxidation to the carboxylic acid is possible by performing the reaction ...
Tollens' test for aldehyde: left side positive (silver mirror), right side negative Ball-and-stick model of the diamminesilver(I) complex. Tollens' reagent (chemical formula ()) is a chemical reagent used to distinguish between aldehydes and ketones along with some alpha-hydroxy ketones which can tautomerize into aldehydes.
