The vibrant and durable colors we see in many high-quality textiles owe much to advanced dye chemistry, particularly the use of vat dyes. These dyes are renowned for their exceptional fastness properties, and at the heart of many of these formulations lies a critical intermediate: 2,6-Diaminoanthraquinone (CAS 131-14-6).

What are Vat Dyes?

Vat dyes are insoluble in water but can be chemically reduced to a soluble form (leuco form) that can penetrate textile fibers. Upon oxidation, they return to their insoluble state within the fiber, resulting in a permanent, highly resistant color. This process makes them ideal for dyeing materials like cotton, linen, and rayon, offering unparalleled wash and light fastness.

The Significance of 2,6-Diaminoanthraquinone

2,6-Diaminoanthraquinone, identified by CAS 131-14-6, is a key precursor in the synthesis of several important vat dyes. Its molecular structure, C14H10N2O2, with amino groups strategically placed on the anthraquinone core, makes it particularly reactive and suitable for creating complex chromophores. A prime example of its application is in the production of Reduced Yellow GCN, a widely used and highly regarded yellow vat dye.

For researchers and product formulators, understanding the properties of this intermediate is crucial. Its reddish-brown crystalline appearance and high purity levels (typically above 99%) are indicators of quality that directly impact the efficacy of the final dye. When you look to purchase 2,6-Diaminoanthraquinone, sourcing from a reliable manufacturer that can provide consistent quality and timely delivery is paramount.
