For professionals in the chemical and materials industry, a deep understanding of a compound's chemical properties is fundamental to its successful application. 3,3'-Sulfonyldianiline, identified by its CAS number 599-61-1, is a key organic intermediate valued for its specific chemical attributes that lend themselves to high-performance material synthesis. As a reputable chemical supplier, NINGBO INNO PHARMCHEM CO.,LTD. provides this compound with meticulous attention to its defining characteristics.

At its core, 3,3'-Sulfonyldianiline is an aromatic diamine with the molecular formula C12H12N2O2S and a molecular weight of approximately 248.3 g/mol. Its structure features two aniline groups linked by a sulfonyl bridge, with the amine groups positioned meta to the sulfonyl group. This specific arrangement influences its reactivity and the properties it imparts to polymers. Typically presented as a white or off-white crystalline powder, its purity level is a critical parameter for industrial users. We consistently supply 3,3'-Sulfonyldianiline with a purity of ≥99.0%, ensuring its efficacy in sensitive applications such as epoxy resin curing and polysulfonamide fiber production.

The physical properties are equally important. With a melting point typically ranging between 170-180°C and a high boiling point of around 542.8°C, it demonstrates significant thermal stability. This inherent thermal resilience is a key reason for its use in applications requiring materials that can withstand elevated temperatures. Furthermore, its solubility characteristics, often noted as slightly soluble in solvents like DMSO and methanol, dictate its handling and processing methods within various manufacturing environments.

As an indispensable organic intermediate, understanding these properties allows formulators to predict and control the outcomes of their reactions. For example, its function as an epoxy resin curing agent relies on the reactive amine hydrogens initiating polymerization and cross-linking. The sulfonyl group contributes to the overall rigidity and thermal stability of the resulting polymer network.
