The product introduced here is Factory Supply 2 - Naphthaldehyde with CAS 66 - 99 - 9 and a low price. 2 - Naphthaldehyde is an important organic compound. The molecular formula of 2 - Naphthaldehyde is C₁₀H₇CHO, with a molecular weight of approximately 156.19 g/mol. It is a pale - yellow to yellow crystalline powder or flake - like solid at room temperature. It has a melting point of around 60 - 62°C and a boiling point of 291 - 293°C. This product is insoluble in water but soluble in organic solvents such as ethanol, ether, and benzene.
2 - Naphthaldehyde has a wide range of applications in various fields. In the field of organic synthesis, it serves as a crucial intermediate. It can be used in the synthesis of various pharmaceutical compounds. For example, it participates in the reaction to form drugs with anti - inflammatory and anti - tumor properties. In the perfume industry, 2 - Naphthaldehyde is used to create unique scents. Its special aromatic structure can add a warm and rich note to perfumes, enhancing the overall fragrance quality and uniqueness.
In the field of dyes, it can be used as a raw material for synthesizing certain dyes. The chromophore of 2 - Naphthaldehyde can impart specific colors and color - fastness properties to dyes, making them suitable for different textile and printing applications.
When using 2 - Naphthaldehyde, strict safety procedures should be followed. First, it should be stored in a cool, dry, and well - ventilated place, away from heat sources and direct sunlight. When handling, appropriate personal protective equipment, such as gloves and goggles, should be worn to avoid skin contact and inhalation of dust.
In the laboratory, when using 2 - Naphthaldehyde for organic synthesis, accurate weighing and measurement are required. It is usually dissolved in a suitable organic solvent first, and then the reaction is carried out under specific reaction conditions, such as temperature, pressure, and reaction time. The reaction progress needs to be monitored through appropriate analytical methods, such as thin - layer chromatography or nuclear magnetic resonance spectroscopy.
In industrial production, large - scale equipment and strict process control are needed. The reaction system should be fully stirred to ensure uniform reaction. After the reaction is completed, the product needs to be purified through appropriate separation and purification methods, such as distillation, recrystallization, etc.
Pharmaceutical Synthesis Case: A pharmaceutical research company planned to synthesize a new anti - inflammatory drug. They used 2 - Naphthaldehyde as a key intermediate. First, 2 - Naphthaldehyde was reacted with a specific amine compound under the catalysis of a Lewis acid. The reaction was carried out in an ethanol solvent at a temperature of 70°C for 5 hours. After the reaction was completed, the product was separated by extraction with dichloromethane. Then, through a series of purification steps, including column chromatography, a high - purity intermediate was obtained. This intermediate was further reacted with other functional groups to form the final anti - inflammatory drug. After animal experiments, the drug showed significant anti - inflammatory effects, indicating the importance of 2 - Naphthaldehyde in pharmaceutical synthesis.
Perfume Creation Case: A well - known perfume brand wanted to create a new men's perfume. The perfumer used 2 - Naphthaldehyde as one of the base notes. By carefully blending 2 - Naphthaldehyde with other essential oils and fragrant substances, such as lavender oil and sandalwood oil, a warm, deep, and long - lasting fragrance was created. The new perfume was well - received in the market, demonstrating the value of 2 - Naphthaldehyde in the perfume industry.
