2,4-Diaminobenzenesulfonic acid

Description:

2,4-Diaminobenzenesulfonic acid, also known as sulfanilic acid, is an organic compound with the molecular formula C6H8N2O2S. It appears as a white to light yellow crystalline solid and is highly soluble in water, making it useful in various applications. This compound features two amino groups (-NH2) and a sulfonic acid group (-SO3H) attached to a benzene ring, which contributes to its acidic properties and reactivity. 2,4-Diaminobenzenesulfonic acid is primarily used in the production of azo dyes and as a reagent in analytical chemistry, particularly in the determination of nitrite and nitrate ions. It also serves as an intermediate in the synthesis of pharmaceuticals and other organic compounds. The presence of both amino and sulfonic acid functional groups allows for diverse chemical reactivity, including coupling reactions and electrophilic substitutions. However, safety precautions should be taken when handling this compound, as it can be harmful if ingested or inhaled, and appropriate protective measures should be employed in laboratory settings.
