CAS 1064778-57-9

2-(4-Fluorophenyl)ethanesulfonic acid, identified by its CAS number 1064778-57-9, is an organic compound characterized by the presence of a sulfonic acid functional group attached to an ethane backbone, which is further substituted with a para-fluorophenyl group. This compound typically exhibits high solubility in polar solvents due to the sulfonic acid group, which enhances its ionic character. It is likely to be a white to off-white solid at room temperature and may have a relatively low melting point. The presence of the fluorine atom in the para position of the phenyl ring can influence its chemical reactivity and biological activity, potentially enhancing lipophilicity and altering interaction with biological targets. As a sulfonic acid, it can participate in acid-base reactions and may serve as a strong acid in various chemical processes. Its applications may extend to pharmaceuticals, agrochemicals, or as a reagent in organic synthesis, although specific uses would depend on further research and development.
