The product is Factory Supply 1,6 - dihydroxynaphthalene with CAS number 575 - 44 - 0 and is offered at a low price. 1,6 - dihydroxynaphthalene is an organic compound with the molecular formula C₁₀H₈O₂. It appears as a white to light - yellow crystalline powder. The compound has a melting point in the range of approximately 138 - 140 °C. Its solubility properties show that it has limited solubility in water but is soluble in organic solvents such as ethanol, ether, and acetone.
1,6 - dihydroxynaphthalene has a wide range of applications in different industries. In the field of cosmetics, it can be used as an antioxidant. Its antioxidant properties help to prevent the oxidation of other components in cosmetic formulations, thus extending the shelf - life of products like creams, lotions, and serums. In addition, it may also contribute to the protection of skin cells from oxidative stress, which is beneficial for anti - aging effects.
In the pharmaceutical industry, 1,6 - dihydroxynaphthalene serves as an important intermediate for the synthesis of various drugs. It can participate in chemical reactions to form more complex molecular structures with specific biological activities. For example, it can be used in the synthesis of drugs for the treatment of certain skin diseases due to its potential anti - inflammatory and anti - microbial properties.
In the dye industry, 1,6 - dihydroxynaphthalene is used as a raw material for the production of dyes. It can react with other chemicals to form color - producing compounds. These dyes are widely used in textile dyeing, providing bright and long - lasting colors to fabrics.
When handling 1,6 - dihydroxynaphthalene, it is essential to follow appropriate safety procedures. Wear appropriate personal protective equipment, including gloves, safety glasses, and a lab coat. When using it in a laboratory or industrial setting, make sure to work in a well - ventilated area to avoid inhalation of dust or vapors.
For dissolution, as it has limited solubility in water, first add it to an appropriate organic solvent. Slowly stir the mixture until the compound is completely dissolved. When using it in a chemical reaction, carefully measure the required amount according to the reaction stoichiometry. Add it gradually to the reaction system under controlled temperature and pressure conditions to ensure the smooth progress of the reaction.
**Cosmetics Case**: A well - known cosmetic company decided to improve the antioxidant performance of its anti - aging serum. They added 1,6 - dihydroxynaphthalene to their formula. After conducting stability tests, they found that the presence of 1,6 - dihydroxynaphthalene effectively inhibited the oxidation of the active ingredients in the serum. The serum maintained its efficacy even after being stored for a longer period at different temperatures. In consumer tests, users reported a significant improvement in skin firmness and a reduction in the appearance of fine lines, indicating the positive impact of 1,6 - dihydroxynaphthalene on skin health.
**Pharmaceutical Case**: A research team was working on developing a new drug for treating acne. They used 1,6 - dihydroxynaphthalene as an intermediate in the synthesis process. After a series of chemical reactions, they obtained a compound with strong anti - inflammatory and anti - microbial properties. In pre - clinical trials on animals, the new drug showed excellent results in reducing acne lesions and inflammation. Further clinical trials on human subjects are currently underway, and the initial results are promising.
**Dye Industry Case**: A textile dyeing factory wanted to develop a new type of red dye. They used 1,6 - dihydroxynaphthalene as one of the key raw materials. By reacting it with other specific chemicals under certain conditions, they successfully synthesized a red dye with high color fastness. When used in textile dyeing, the dye provided a bright and vivid red color to the fabrics. The dyed fabrics passed various color fastness tests, including washing, rubbing, and light fastness tests, indicating the high quality of the dye prepared from 1,6 - dihydroxynaphthalene.
