CAS 19866-50-3
:2-Pentenoic acid, 3-methyl-, (E)-
Description:
2-Pentenoic acid, 3-methyl-, (E)-, also known by its CAS number 19866-50-3, is an unsaturated carboxylic acid characterized by a five-carbon chain with a double bond between the second and third carbon atoms, and a methyl group attached to the third carbon. This compound exhibits typical properties of carboxylic acids, including the ability to form hydrogen bonds, which contributes to its relatively higher boiling point compared to alkanes of similar molecular weight. The (E)- configuration indicates that the highest priority substituents on either side of the double bond are on opposite sides, affecting its reactivity and physical properties. It is a colorless to pale yellow liquid with a distinctive odor, and it is soluble in water due to the presence of the carboxylic acid functional group. 2-Pentenoic acid, 3-methyl- is used in organic synthesis and may serve as an intermediate in the production of various chemical compounds, including pharmaceuticals and agrochemicals. Its reactivity is influenced by the presence of both the double bond and the carboxylic acid group, making it a versatile building block in organic chemistry.
