CAS 6089-09-4: 4-Pentynoic acid

Description: 4-Pentynoic acid, with the CAS number 6089-09-4, is an alkyne carboxylic acid characterized by a five-carbon chain featuring a triple bond between the fourth and fifth carbon atoms. It has a molecular formula of C5H6O2, indicating the presence of a carboxylic acid functional group (-COOH) and an alkyne functional group. This compound is typically a colorless to pale yellow liquid with a distinct odor. It is soluble in organic solvents and exhibits limited solubility in water due to its hydrophobic carbon chain. 4-Pentynoic acid can participate in various chemical reactions, including esterification and addition reactions, making it useful in organic synthesis and as an intermediate in the production of pharmaceuticals and agrochemicals. Additionally, it may exhibit some degree of acidity, typical of carboxylic acids, allowing it to act as a proton donor in chemical reactions. Safety precautions should be taken when handling this compound, as it may be irritating to the skin and eyes.
