The product <|产品名称1|> refers to High Quality sodium 2 - naphthol - 7 - sulfonate with CAS number 135 - 55 - 7. It is available at the best price in the market. Sodium 2 - naphthol - 7 - sulfonate is an important organic compound. Its chemical formula is C₁₀H₇O₄SNa. It usually appears as a white to off - white powder, with good solubility in water. This compound is known for its high purity and stability, which are ensured through strict quality control measures during the manufacturing process. In terms of storage, it should be kept in a cool, dry place, away from direct sunlight and heat sources to prevent degradation and maintain its chemical properties.
Sodium 2 - naphthol - 7 - sulfonate has a wide range of applications in various industries. In the dye industry, it serves as a crucial intermediate for the synthesis of a variety of dyes. It can react with different reagents to form dyes with excellent color fastness and brightness. These dyes are widely used in textile printing and dyeing, providing vivid and long - lasting colors to fabrics. In the pharmaceutical industry, this compound can be used in the synthesis of certain drugs. Its specific chemical structure allows it to participate in reactions that lead to the production of bioactive substances, which may have anti - inflammatory, antibacterial or other therapeutic effects. Additionally, it is also used in the field of analytical chemistry. It can be used as a reagent for the detection and determination of certain metal ions due to its ability to form complexes with specific metals, which can be detected through various analytical methods.
When using sodium 2 - naphthol - 7 - sulfonate, it is necessary to follow strict safety procedures. First, appropriate personal protective equipment, such as gloves and goggles, should be worn to avoid direct contact with the skin and eyes. When dissolving the product in water or other solvents, add it slowly to the solvent under stirring to ensure uniform dispersion. The dosage should be determined according to the specific application requirements. For example, in the dye synthesis process, the amount of sodium 2 - naphthol - 7 - sulfonate added depends on the type and quantity of the dye to be synthesized. It is recommended to conduct small - scale experiments first to determine the optimal dosage and reaction conditions. After use, the product container should be tightly sealed to prevent moisture and air from entering, which may affect the quality of the remaining product.
A textile dyeing factory used sodium 2 - naphthol - 7 - sulfonate in the production of a new type of reactive dye. They first conducted a series of small - scale trials to optimize the reaction conditions. They started with different ratios of sodium 2 - naphthol - 7 - sulfonate to other reactants. By carefully controlling the temperature, pH value and reaction time, they found that when the molar ratio of sodium 2 - naphthol - 7 - sulfonate to the main dye precursor was 1:1.2, and the reaction was carried out at a temperature of 80°C and a pH of 8, the yield of the reactive dye was the highest. After large - scale production, the dyed fabrics showed excellent color fastness to washing, rubbing and light. The colors were bright and uniform, which significantly improved the quality of the textile products. The factory was able to expand its market share and increase its profits due to the high - quality products made possible by the use of sodium 2 - naphthol - 7 - sulfonate.
