Product Name: High Quality 1,5-Dihydroxy naphthalene CAS 83-56-7 With Low Price
CAS Number: 83-56-7
Appearance: Usually in the form of a white to light - yellow crystalline powder.
Purity: Our 1,5 - Dihydroxy naphthalene is of high quality, with a purity level that can meet various industrial and research requirements. The specific purity can be customized according to customers' needs.
Solubility: It is sparingly soluble in water but more soluble in organic solvents such as ethanol, ether, and acetone.
Storage Conditions: Store in a cool, dry place away from direct sunlight and sources of heat. Keep the container tightly closed to prevent moisture absorption and oxidation.
1,5 - Dihydroxy naphthalene has a wide range of applications in different fields:
Chemical Synthesis: It serves as an important intermediate in the synthesis of various dyes, pigments, and pharmaceuticals. For example, it can be used to synthesize azo dyes with excellent color - fastness properties. In pharmaceutical synthesis, it may participate in the construction of certain drug molecules with specific biological activities.
Photographic Industry: Due to its ability to react with certain silver salts, it is used in the development process of some black - and - white photographic films and papers. It helps to reduce silver ions to metallic silver, forming the image on the photographic medium.
Analytical Chemistry: It can be used as a reagent in analytical methods. For instance, it can react with some metal ions to form complexes with characteristic absorption spectra, which can be used for the quantitative and qualitative analysis of these metal ions.
Handling Precautions: When handling 1,5 - Dihydroxy naphthalene, it is recommended to wear appropriate personal protective equipment, including gloves, safety goggles, and a laboratory coat. Avoid inhalation of dust and direct contact with skin and eyes. In case of contact, immediately rinse with plenty of water and seek medical advice if necessary.
Usage in Chemical Synthesis: In a typical chemical synthesis reaction, dissolve 1,5 - Dihydroxy naphthalene in a suitable organic solvent under a nitrogen atmosphere to prevent oxidation. Then, add other reactants gradually according to the reaction conditions, such as temperature and reaction time. Stir the reaction mixture vigorously to ensure uniform reaction.
Usage in Photographic Industry: Prepare a solution of 1,5 - Dihydroxy naphthalene with the appropriate concentration according to the requirements of the photographic process. Immerse the photographic material in this solution for the specified time, and then follow the subsequent development, fixing, and washing steps.
Case Study 1 - Dye Synthesis
A dye manufacturing company needed to produce a new type of azo dye with high color - fastness. They used 1,5 - Dihydroxy naphthalene as one of the key intermediates. First, they dissolved 1,5 - Dihydroxy naphthalene in ethanol at a temperature of 60°C. Then, they added a diazonium salt solution drop - by - drop under stirring. The reaction was carried out for 2 hours at this temperature. After purification, they obtained a high - quality azo dye that showed excellent color - fastness on cotton fabrics, which increased the company's product competitiveness in the market.
Case Study 2 - Photographic Application
A small - scale photographic studio wanted to improve the quality of their black - and - white prints. They decided to use 1,5 - Dihydroxy naphthalene in their development process. They prepared a developer solution with the recommended concentration of 1,5 - Dihydroxy naphthalene. After using this new developer, the resulting prints had better contrast and finer grain, which satisfied their customers and attracted more business.
