Understanding the scientific basis of chemical compounds is fundamental for B2B decision-makers, from R&D scientists to procurement specialists. Acid Green 3, identified by CAS 4680-78-8, is a prime example of a chemical with specific properties that dictate its wide-ranging industrial utility. This article explores the scientific aspects of Acid Green 3, its applications, and key considerations for sourcing from manufacturers and suppliers.

Scientifically, Acid Green 3 is classified as a water-soluble triphenylmethane dye. Its chemical structure, represented by MF: C37H35N2NaO6S2 and a molecular weight of 690.80, endows it with its characteristic properties. The presence of sulfonate groups (SO3Na) makes it soluble in water, a crucial characteristic for many dyeing and formulation processes. Its appearance as a light green crystalline powder is a direct result of its molecular composition and solid-state structure.

The melting point of Acid Green 3, typically around 255 °C with decomposition, indicates its thermal stability under normal processing conditions for many applications. The Color Index (CI) number 42085 further categorizes it within a specific group of dyes, aiding in identification and cross-referencing within the industry.

The industrial applications of Acid Green 3 are a direct consequence of its properties. Its affinity for protein fibers makes it an excellent choice for dyeing silk and wool, providing vibrant, consistent green shades. In the realm of inks, its solubility and hue contribute to clear, sharp print results. The formulation of leather finishes and shoe creams utilizes Acid Green 3 to achieve desired aesthetic qualities. Furthermore, its incorporation into paper products and various cleaning agents highlights its versatility beyond traditional textile dyeing. For scientists and formulators, understanding these properties is key to optimizing its use in specific contexts.

When looking to 'buy Acid Green 3,' technical specifications such as purity (commonly 98%) are paramount. A high-purity product ensures predictable outcomes and minimizes the risk of interference in sensitive chemical reactions or formulations. For procurement professionals, sourcing from reliable manufacturers, particularly those in China known for their large-scale production capabilities (e.g., 100 tons), offers both quality assurance and cost efficiencies.

Identifying a trustworthy Acid Green 3 supplier involves examining their adherence to quality standards, their ability to provide comprehensive documentation (like COAs and SDS), and their responsiveness to inquiries regarding 'Acid Green 3 price' and availability. The scientific community relies on these assurances to maintain the integrity of their research and product development processes.

In conclusion, the scientific understanding of Acid Green 3's properties underpins its value in diverse industrial sectors. By appreciating its chemical nature and sourcing it from reputable manufacturers, businesses can effectively leverage this dye to achieve their coloration goals.
