CAS 106086-27-5

4-Formyl-5-hydroxybenzenesulfonic acid

Description:

4-Formyl-5-hydroxybenzenesulfonic acid, with the CAS number 106086-27-5, is an organic compound characterized by the presence of a formyl group (-CHO) and a hydroxyl group (-OH) attached to a benzene ring that also contains a sulfonic acid group (-SO3H). This compound is typically a white to off-white solid and is soluble in water due to the sulfonic acid functionality, which enhances its polarity. The presence of both the hydroxyl and sulfonic acid groups contributes to its acidic properties and potential reactivity in various chemical reactions, such as electrophilic substitution or condensation reactions. It may be used in various applications, including as a reagent in organic synthesis, in dye chemistry, or as an intermediate in the production of other chemical compounds. Its structural features suggest it may also exhibit biological activity, making it of interest in pharmaceutical research. Safety data should be consulted for handling and usage, as with any chemical substance.
