ZhonghanProduct Overview
Assuming its molecular formula is C₁₀H₁₄O₃S (hypothetical molecular formula), the estimated molecular weight is about 214.28. Under normal conditions, it is speculated that it may be a white crystalline powder with good stability and is not easy to decompose under normal conditions. However, under extreme conditions such as high temperature, strong acid and alkali, structural changes may occur, triggering chemical reactions. It is preliminarily assumed that its melting point is 130-135℃, which is crucial for its separation and purification in chemical production.

ZhonghanPhysical properties
If it is a white crystalline powder, it will be clearly recognizable in appearance, making it easy to identify during production and use. Its density may be between 1.2 and 1.3 g/cm³, which means that in a liquid environment, it will be in a certain sedimentation position. It is speculated that it has low volatility and can remain solid for a long time, reducing losses during storage and use. In terms of solubility, it may be slightly soluble in water, but easily soluble in organic solvents such as ethanol and chloroform, which enables it to be better dispersed and participate in reactions in organic reaction systems.
ZhonghanApplication Areas
In the chemical industry, it may be used as a key monomer for synthesizing special polymers to improve the mechanical properties and heat resistance of polymers. In the field of materials science, the compound is introduced to modify existing materials, such as enhancing the oxidation resistance of metal materials and improving the fatigue resistance of composite materials. In the pharmaceutical industry, it may be used as an important intermediate for synthesizing certain drugs, participating in the construction of molecular structures with specific pharmacological activities and assisting in the research and development of new drugs.
