Cyclobutanecarboxylic acid, identified by the CAS number 3721-95-7, is an organic compound characterized by a cyclobutane ring attached to a carboxylic acid group. Its molecular formula is C5H8O2, giving it a molecular weight of approximately 100.12 g/mol. This structure provides it with unique reactivity and physical properties that make it an important intermediate in various chemical syntheses. NINGBO INNO PHARMCHEM CO.,LTD. specializes in supplying high-quality Cyclobutanecarboxylic Acid to meet the demands of researchers and manufacturers.

The cyclobutane ring itself is a strained four-membered carbocycle, which influences the overall properties of the molecule. This ring system contributes to the compound's chemical behavior, making it a valuable building block for introducing specific structural motifs into larger molecules. The carboxylic acid functional group (-COOH) imparts acidic properties, allowing it to participate in reactions typical of carboxylic acids, such as esterification, amide formation, and salt formation. Its pKa of 4.785 indicates it is a weak acid.

Physically, Cyclobutanecarboxylic acid appears as a colorless to slightly amber liquid. Key physical properties include a melting point of -7.5°C and a boiling point of 195°C. This relatively low melting point means it is typically encountered as a liquid under standard laboratory conditions. The refractive index of 1.444 and a density of 1.047 g/mL at 25°C are also important parameters for its identification and use. While it has limited solubility in water, it is miscible with many organic solvents, which is advantageous for its incorporation into various reaction systems.
