The world of dyes is a complex interplay of chemistry and color science, with intermediates forming the foundational building blocks for vibrant and durable pigments. Among these vital compounds is 1,4-Diamino-2,3-dihydroanthraquinone (CAS 81-63-0), a key intermediate that plays a significant role in the synthesis of various dyes, particularly anthraquinone-based colorants. For R&D scientists and product formulators in the chemical manufacturing sector, understanding the properties and applications of this intermediate is crucial for developing new shades and improving existing dye formulations. This article delves into its importance and highlights why sourcing it from a reliable manufacturer is essential.

1,4-Diamino-2,3-dihydroanthraquinone: A Key Intermediate for Color

With its distinct violet brown powder appearance and high purity (typically 96%min assay), 1,4-Diamino-2,3-dihydroanthraquinone (CAS 81-63-0) is a versatile precursor in organic synthesis. Its molecular structure, C14H12N2O2, allows it to undergo further chemical transformations to yield a range of specialized dyes. The compound's low water content, usually less than 1.0%, also ensures its stability and effectiveness during synthesis processes. As a dedicated manufacturer, we ensure that each batch of this critical intermediate meets stringent quality standards, providing formulators with the confidence needed to buy and utilize it in their production lines.

Applications in Dye Manufacturing

The primary application of 1,4-Diamino-2,3-dihydroanthraquinone lies in its role as a precursor to a variety of dyes. It is integral to the production of vat dyes and anthraquinone dyes, known for their excellent colorfastness, brightness, and resistance to fading. These properties make them highly sought after in the textile industry, printing, and other applications where color longevity is critical. By modifying the molecular structure of this intermediate, manufacturers can fine-tune the resulting dye's hue, solubility, and application properties. For companies looking to buy reliable dye intermediates, understanding the synthetic pathways and required purity levels is key. Our company, as a supplier in China, offers this compound to support your innovation in color technology.

Sourcing and Quality Assurance

When sourcing 1,4-Diamino-2,3-dihydroanthraquinone, it's important to partner with a manufacturer that can guarantee consistent quality and supply. Factors such as proper storage (cool, dry, out of direct sunlight) and appropriate packaging (e.g., 25kg/drum) are indicative of a supplier's commitment to product integrity. R&D scientists and procurement managers often seek suppliers who can provide detailed specifications, sample quantities for testing, and competitive pricing for bulk orders.
