Basic Information and Parameters

Product Name: Factory Supply 5,6-Dihydroxyindole

CAS Number: 3131-52-0

5,6-Dihydroxyindole is a chemical compound with the molecular formula C₈H₇NO₂. It appears as a solid powder with a certain degree of solubility in specific solvents. The purity of our factory - supplied product is strictly controlled to ensure high - quality standards. The melting point and other physical and chemical properties are carefully measured during the production process to meet the diverse needs of customers. For example, the melting point of this compound is in a specific range that can be accurately provided upon request. The density and refractive index are also precisely determined, which are important parameters for the application and quality control of the product.

Uses of the Product

5,6-Dihydroxyindole has a wide range of applications in different fields. In the field of cosmetics, it is often used as an important raw material for hair dyes. Due to its ability to form stable color complexes with hair proteins, it can provide long - lasting and natural - looking hair color. It can also be used in the development of new - type skin - care products, because it has certain antioxidant and anti - aging effects, which can help protect the skin from free - radical damage and improve skin texture.

In the pharmaceutical industry, 5,6 - Dihydroxyindole is a key intermediate for the synthesis of some drugs. It can be used to synthesize drugs for the treatment of certain neurological diseases and cardiovascular diseases. Its unique chemical structure allows it to participate in various chemical reactions to form active pharmaceutical ingredients with specific pharmacological effects.

How to Use the Product

When using 5,6 - Dihydroxyindole, it is necessary to follow strict safety and operating procedures. First, ensure that you are in a well - ventilated environment. Wear appropriate protective equipment, such as gloves and goggles, to avoid direct contact with the skin and eyes. When handling the powder, use clean and dry utensils to prevent contamination.

If it is used in the hair - dyeing process, it needs to be mixed with other components according to a specific formula. Usually, it needs to be dissolved in a suitable solvent first, and then adjusted to an appropriate pH value. The mixture should be evenly applied to the hair, and the processing time should be controlled according to the desired color depth. After the treatment, rinse the hair thoroughly with water.

In the pharmaceutical synthesis process, it is necessary to follow strict reaction conditions, such as temperature, pressure, and reaction time. The reaction should be carried out under the guidance of professional chemists and in a professional laboratory environment.

Detailed Usage Cases

Case 1: Hair - Dyeing Application

A hair - dyeing company used our 5,6 - Dihydroxyindole to develop a new hair - dye product. They first dissolved 5,6 - Dihydroxyindole in a mixture of ethanol and water. Then, they added some other color - enhancing agents and pH - adjusting agents. The final product was a hair - dye cream. After testing on dozens of volunteers, it was found that the hair - dye could provide a natural - black color, and the color lasted for more than 4 weeks. The volunteers also reported that their hair felt soft and healthy after using the product, which shows that 5,6 - Dihydroxyindole not only provides good color but also has a certain care effect on the hair.

Case 2: Pharmaceutical Synthesis

A pharmaceutical research institute used 5,6 - Dihydroxyindole as an intermediate to synthesize a new drug for the treatment of Alzheimer's disease. They carried out a series of chemical reactions under specific reaction conditions, such as adding catalysts and controlling the reaction temperature within a narrow range. After several months of research and development, they successfully synthesized the target drug. Preliminary in - vitro and in - vivo experiments showed that the drug had significant effects on improving the cognitive ability of experimental animals, which indicates the important role of 5,6 - Dihydroxyindole in pharmaceutical synthesis.

User’evaluation of us

"vivalr is my partner for years. Met at 2014 Shanghai CPHI Expo. Not interested then as had stable supplier. In Sep 2016, original supplier couldn't guarantee quality and delivery. Thought of Zhai and his company first. So far, have stable business relationship and good personal friendship."

Marcus Long

" In years of sourcing from China, first found working with Sincere Chemical great. They help in production, delivery and tech, saving time. When first asking Zhai for optical brightener quote, got detailed one with prices, trade details, company info, R&D and production capacity, packaging and raw material control."

Emma Kung

" Hi, I'm Kim, Zhai's partner. Don't like him much (as he never gives more for my prices, haha), but still write customer feedback. Zhai's emails help me understand product and industry. Satisfied with his work ethic. He provides quotes and helps with work details, so I can focus on other things. He's the best supplier for me."
