Its physical properties are unique, and the following is a detailed description of Jun:
From the perspective of its properties, it often takes a solid form. Due to the strong intermolecular force, it maintains a solid state at room temperature and pressure, and its stability is quite high. And because the molecular structure is rich in sulfonic acid groups (-SO 🥰 H), the group has strong hydrophilicity, so this compound is easily soluble in water and can show good solubility in water. This property is of great significance in many chemical applications, such as in aqueous solution chemical reaction systems, it can be used as an excellent carrier for reactants or catalysts.
Furthermore, its melting point is also a key physical property. However, due to the complex structure and many intermolecular interactions, its melting point is high. A higher temperature is required to break the intermolecular force and transform it from a solid state to a liquid state.

This substance may have applications in chemical, pharmaceutical, materials and other fields. However, its safety needs to be considered more.
From the perspective of chemical structure, it contains many functional groups such as amino groups and sulfonic acid groups. Amino groups are alkaline to a certain extent, or can react with other substances. Under specific conditions, or produce products with different properties, which may affect their safety. Although sulfonic acid groups often make compounds have good water solubility, they may also affect their metabolism in organisms and their interaction with biomacromolecules.
If it involves human contact, its particles or aerosols enter the lungs through inhalation, or irritate the respiratory tract, causing cough, asthma and other discomfort, long-term or lung damage. Skin contact, or penetrate the skin, causing allergies, inflammation and other reactions, depending on the skin sensitivity of different individuals, the degree of reaction varies. If ingested carelessly, it will react in the gastrointestinal tract or with the components of the digestive fluid, affect the digestive function, and even be absorbed into the blood, circulated to the whole body, and affect the functions of various organs.
At the environmental level, if this substance is released into the water, it may affect the ecology of the water body. Due to its complex structure, it is difficult for microorganisms to degrade or store, or cause it to accumulate in the water body, affecting the growth and reproduction of aquatic organisms, and destroying the ecological balance. If it enters the soil, or interacts with soil components, it will affect the soil properties and fertility, and then affect plant growth.
In short, the safety of this substance requires rigorous experiments and research to comprehensively evaluate its potential impact on human health and the environment, so as to ensure safety during use.
