Overview
Azoresorcinol is an organic compound belonging to the azo dye family. It is widely used as an intermediate in the synthesis of dyes and pigments, particularly in the textile industry. The compound is known for its stability and ability to produce vibrant colors when processed further. Azoresorcinol is synthesized through diazotization and coupling reactions involving aromatic amines. Its molecular structure includes an azo group (-N=N-) bonded to aromatic rings, which is characteristic of many synthetic dyes.
Physical and Chemical Properties
Azoresorcinol appears as an orange to brown crystalline powder. It has a molecular weight of 213.24 g/mol and a melting point around 200-205°C. The compound is soluble in organic solvents like ethanol and acetone but has limited solubility in water. Its chemical stability makes it suitable for high-temperature dyeing processes. The presence of both amino and hydroxyl groups in its structure allows for versatile chemical modifications, enabling its use in various dye formulations.
Main Applications
The primary application of Azoresorcinol is in the textile industry, where it serves as an intermediate for producing azo dyes. These dyes are used to color fabrics, leather, and paper. The compound's ability to form stable, vivid colors makes it valuable for synthetic dye manufacturing. Beyond textiles, Azoresorcinol is also used in research and development for creating specialized pigments and coatings. Its chemical properties allow it to be incorporated into formulations requiring high color fastness and durability.
Safety and Storage
Azoresorcinol requires careful handling due to its potential health hazards. Prolonged exposure can cause skin and eye irritation, and inhalation of dust should be avoided. Proper personal protective equipment (PPE), including gloves and goggles, is recommended during handling. Storage conditions should include a cool, dry environment away from direct sunlight and moisture. The compound should be kept in tightly sealed containers to prevent degradation. Spills should be cleaned immediately using appropriate absorbent materials.
B2B Procurement Guide
When procuring Azoresorcinol, B2B buyers should verify the CAS number (104-23-4) and purity specifications. Reputable suppliers typically provide certificates of analysis (CoA) to confirm quality. Bulk purchases often come with discounts, so inquire about volume pricing. It's advisable to source from suppliers with a track record in chemical distribution, ensuring compliance with safety and environmental regulations. Shipping and storage requirements should also be discussed to maintain product integrity during transit.
