2,5-Dihydroxybenzenesulfonic acid

Description:
2,5-Dihydroxybenzenesulfonic acid, also known as 2,5-Dihydroxy-phenylsulfonic acid, is an aromatic sulfonic acid characterized by the presence of two hydroxyl (-OH) groups and a sulfonic acid (-SO3H) group attached to a benzene ring. This compound is typically a white to light yellow crystalline solid that is soluble in water due to the polar nature of its functional groups. It exhibits acidic properties, which can influence its reactivity and interactions in various chemical processes. The presence of hydroxyl groups allows for potential hydrogen bonding, enhancing its solubility and reactivity with other compounds. 2,5-Dihydroxybenzenesulfonic acid is often used in the synthesis of dyes, pigments, and as a reagent in organic chemistry. Additionally, it may serve as an intermediate in the production of other chemical compounds. Safety precautions should be observed when handling this substance, as it may cause irritation to the skin and eyes.
