The product is High Quality 2,5-dihydroxyterephthalic(DHTA) with the CAS number 610 - 92 - 4. It is offered at the best price in the market. DHTA is an organic compound with a specific chemical structure. The molecular formula of 2,5-dihydroxyterephthalic acid is (C_8H_6O_6). Its molecular weight is approximately 198.13 g/mol. It usually appears as a white to off - white crystalline powder. This product is known for its high purity, which ensures reliable performance in various applications.
2,5-dihydroxyterephthalic acid has a wide range of uses. In the field of materials science, it can be used as a monomer in the synthesis of high - performance polymers. These polymers may have excellent heat resistance, mechanical properties, and chemical stability, making them suitable for applications in aerospace, automotive, and electronic industries. For example, they can be used to manufacture parts that require high strength and heat resistance, such as engine components in cars and circuit boards in electronics.
In the field of pharmaceuticals, DHTA may serve as an intermediate in the synthesis of certain drugs. Its unique chemical structure can participate in specific chemical reactions to form bio - active compounds. Additionally, it can also be used in the development of new drug delivery systems due to its ability to interact with biological molecules.
In the field of environmental science, DHTA can be used in the treatment of heavy metal pollution. It can form stable complexes with heavy metal ions, which helps in the removal of these pollutants from water and soil.
When using High Quality 2,5-dihydroxyterephthalic(DHTA), it is important to follow proper safety procedures. Wear appropriate personal protective equipment, such as gloves and goggles, to avoid direct contact with the product. In a laboratory or industrial setting, use it in a well - ventilated area to prevent inhalation of dust.
For chemical synthesis, DHTA should be accurately weighed according to the reaction recipe. It can be dissolved in suitable solvents, such as dimethyl sulfoxide (DMSO) or N,N - dimethylformamide (DMF), depending on the reaction requirements. The reaction conditions, including temperature, pressure, and reaction time, should be carefully controlled to ensure the desired reaction outcome.
In the treatment of heavy metal pollution, the appropriate dosage of DHTA should be determined based on the concentration of heavy metal ions in the sample. It can be added to the contaminated water or soil, and then the mixture should be stirred thoroughly to promote the complexation reaction.
Case 1: Polymer Synthesis
A research team in an aerospace company aimed to develop a new high - performance polymer for aircraft engine components. They used 2,5-dihydroxyterephthalic acid as one of the monomers. First, they accurately weighed DHTA and other co - monomers according to the designed molar ratio. Then, they dissolved these monomers in DMF and added a suitable catalyst. The reaction mixture was heated under reflux for several hours at a specific temperature. After the reaction, the resulting polymer was purified by precipitation in a non - solvent. The final polymer had excellent heat resistance and mechanical strength, which met the requirements for aircraft engine components.
Case 2: Heavy Metal Pollution Treatment
An environmental protection agency was dealing with a water sample contaminated with lead ions. They determined the concentration of lead ions in the water and calculated the appropriate amount of DHTA to be added. They added DHTA to the water sample and stirred the mixture for 30 minutes. After that, they found that the concentration of lead ions in the water decreased significantly due to the formation of lead - DHTA complexes. The complexes could be easily removed by filtration, achieving effective treatment of the heavy metal - contaminated water.
