Understanding the intrinsic properties of chemical compounds is fundamental to their effective application. NINGBO INNO PHARMCHEM CO.,LTD. is pleased to offer insights into the key characteristics of 1,3-Bis(2-hydroxyethoxy)benzene (CAS 102-40-9) and how these properties translate into significant performance enhancements in materials science.

1,3-Bis(2-hydroxyethoxy)benzene is an aromatic diol, characterized by a benzene ring substituted with two hydroxyethoxy groups at the meta positions. This molecular architecture dictates its behavior and utility. Its chemical formula, C10H14O4, and molecular weight of approximately 198.22 g/mol provide the basic quantitative definition. Physically, it typically presents as a white to almost white powder or lump, with a melting point around 90°C, indicating it's a solid at room temperature. This physical state is conducive to handling and incorporation into various manufacturing processes.

The presence of two primary hydroxyl (-OH) groups is central to its functionality. These hydroxyl groups are highly reactive, readily participating in esterification and urethane formation reactions. This reactivity makes 1,3-Bis(2-hydroxyethoxy)benzene an excellent candidate for polymerization processes. As a chain extender in polyurethane elastomers, these hydroxyl groups react with isocyanate (-NCO) groups on prepolymers. This reaction builds longer polymer chains and forms the hard segments that are crucial for imparting strength, stiffness, and thermal resistance to the final elastomer. The aromatic nature of the benzene ring within its structure further contributes to the rigidity and thermal stability of these hard segments, leading to enhanced high-temperature performance and creep resistance in the polyurethane product.

In polyester synthesis, the diol functionality allows it to react with dicarboxylic acids (or their derivatives) through polycondensation. The resulting polyesters often exhibit a favorable balance of properties, including good thermal stability and mechanical strength, attributed to the incorporated aromatic structure. The length and flexibility of the ethoxy linkages can also influence the glass transition temperature (Tg) and overall flexibility of the polyester, offering a degree of tunability for specific applications.

Furthermore, its solubility characteristics are important for processing. While slightly soluble in water, it exhibits better compatibility with organic solvents and polymer matrices. This property is essential for ensuring homogeneous mixing during compound formulation. The chemical stability of 1,3-Bis(2-hydroxyethoxy)benzene under typical processing conditions is also a key advantage, preventing degradation and maintaining its functional integrity.
