Overview
Dihydroxyanthraquinone Violet is a synthetic dye derived from anthraquinone, known for its vibrant violet color. It is widely used in industries requiring stable and fade-resistant pigments. The compound's molecular structure ensures durability under heat and light, making it a preferred choice for high-performance applications. Its synthesis involves the hydroxylation of anthraquinone, resulting in a product with excellent solubility in organic solvents. This dye is particularly valued in textile manufacturing, where color retention is critical.
Physical and Chemical Properties
Dihydroxyanthraquinone Violet appears as a fine violet crystalline powder with a molecular weight of 240.21 g/mol. It has a density of approximately 1.4 g/cm³ and a melting point range of 200-220°C. The compound is insoluble in water but dissolves readily in ethanol and other organic solvents. Its key chemical properties include high thermal stability and resistance to oxidation, which contribute to its longevity in dyed fabrics and printed materials. The dye's vivid color is attributed to its conjugated double-bond system, which absorbs specific wavelengths of light.
Main Applications
This dye is primarily used in the textile industry for dyeing synthetic and natural fibers, offering excellent wash and light fastness. It is also employed in the production of inks for printing and packaging, where color consistency is essential. Additionally, Dihydroxyanthraquinone Violet serves as a pigment in plastics and coatings, providing long-lasting color without degradation. Its stability under UV exposure makes it suitable for outdoor applications, such as automotive paints and architectural coatings.
Safety and Storage
While Dihydroxyanthraquinone Violet is not highly toxic, precautions should be taken to avoid inhalation or skin contact. Protective gloves and masks are recommended during handling. The dye should be stored in a cool, dry environment, away from direct sunlight and moisture, to prevent clumping or degradation. In case of accidental exposure, rinse affected areas with water and seek medical advice if irritation persists. Proper disposal methods should be followed to minimize environmental impact.
B2B Procurement Guide
When purchasing Dihydroxyanthraquinone Violet, buyers should prioritize suppliers who provide certificates of analysis (CoA) to verify purity and composition. Bulk orders typically offer cost advantages, but storage capacity should be considered to maintain product quality. It is advisable to request samples for testing before large-scale procurement to ensure compatibility with specific applications. Pricing varies based on purity levels and order volume, with discounts often available for repeat customers.
