CAS 5363-54-2

p-formylbenzenesulphonic acid

Description:

p-Formylbenzenesulphonic acid, with the CAS number 5363-54-2, is an aromatic sulfonic acid characterized by the presence of both a formyl group (-CHO) and a sulfonic acid group (-SO3H) attached to a benzene ring. This compound typically appears as a white to light yellow solid and is soluble in water due to the polar nature of the sulfonic acid group. It is known for its reactivity, particularly in electrophilic aromatic substitution reactions, where the formyl group can direct further substitutions on the benzene ring. The sulfonic acid group enhances the compound's acidity and solubility, making it useful in various chemical syntheses and applications, including as an intermediate in the production of dyes and pharmaceuticals. Additionally, p-formylbenzenesulphonic acid can participate in condensation reactions, contributing to the formation of more complex organic molecules. Safety precautions should be observed when handling this compound, as with many sulfonic acids, due to its corrosive nature.

4-Sulfobenzaldehyde Hydrate

CAS: 5363-54-2

4-Sulfobenzaldehyde hydrate is a chemical intermediate that is used for the production of detergents and other products. This compound can be prepared by reacting phenol with sulfur dioxide in the presence of a chlorinating agent. 4-Sulfobenzaldehyde hydrate can also be obtained by reacting aniline or phenol with sodium hypochlorite in the presence of a catalyst. The biphenyl molecule contains two benzene rings joined by a single carbon atom, and this compound can be oxidized to form biphenyldicarboxylic acid, which has fluorescent properties. 4-Sulfobenzaldehyde hydrate is an acid and cleaves in water to form hydrochloric acid and benzoic acid.
