Product Specification:

Product Description:
3,3'-Diamino - 4,4'-dihydroxydiphenyl sulfone commonly shows as a white to light - beige solid under normal circumstances. Structurally, it features a central sulfone group (-SO?-), with two phenyl rings attached on either side. Each phenyl ring has an amino group (-NH?) at the 3 - position and a hydroxyl group (-OH) at the 4 - position.

Due to the non - polar nature of the phenyl rings and the relatively large molecular structure, its solubility in water is low. It exhibits better solubility in polar organic solvents like ethanol and dimethyl sulfoxide (DMSO). The two amino and two hydroxyl groups endow it with distinct reactivity. The amino groups are prone to react with acylating agents in acylation reactions, and the hydroxyl groups can participate in substitution reactions with electrophiles.

During storage, it should be kept away from light and air. Oxidation by air may gradually change its color and degrade its properties. In organic synthesis, it serves as an important building block for constructing complex molecules. It finds applications in the synthesis of high - performance polymers, contributing to enhanced mechanical and thermal properties. It is also utilized in pharmaceutical research for introducing specific functional groups. Store it in a cool, dark, and tightly - sealed container to maintain its quality.

Application: 

It is the key raw material of organic synthesis. In the synthesis of high performance polymers, mechanical and thermal properties of materials can be enhanced; In pharmaceutical research, it is used to introduce specific functional groups to help develop new drugs.
