In the vibrant world of colorants, the quality of intermediates directly dictates the brilliance and durability of the final product. Disodium 1,5-Naphthalenedisulfonate (CAS 1655-29-4) is a cornerstone chemical, playing a critical role in the formulation and synthesis of a wide range of dyes. For purchasing managers in the textile and printing industries, understanding the value and sourcing of this compound is essential for maintaining product quality and competitiveness.

Disodium 1,5-Naphthalenedisulfonate, typically supplied as a high-purity white powder crystal (often ≥99.0%), serves as a vital intermediate in the production of azo and reactive dyes. Its chemical structure facilitates the creation of dyes with excellent color yield, superior lightfastness, and wash fastness, attributes highly valued in textile applications. Furthermore, its effectiveness extends to printing inks and coatings, where it contributes to pigment dispersion, ensuring uniformity and vibrancy. Businesses looking to buy Disodium 1,5-Naphthalenedisulfonate for their dye formulations seek out reliable manufacturers who can consistently deliver this quality.

For efficient procurement, it's beneficial to research the price of CAS 1655-29-4 and identify dependable suppliers. Many leading dye manufacturers rely on specialized Chinese chemical companies for their supply of this critical intermediate. These suppliers often provide a range of packaging options, such as 25KG/DRUM or 800KG/BAG, to suit varying production scales. When selecting a supplier, consider their adherence to quality standards and their ability to provide essential technical documentation, like COAs, which attest to the product's purity and suitability for your specific dye formulations.

Beyond its primary role in dye synthesis, the dispersing properties of Disodium 1,5-Naphthalenedisulfonate can also be beneficial in other industrial applications, though its main value proposition remains firmly rooted in coloration. As the demand for high-performance textiles and vivid printing continues, the strategic sourcing of this key intermediate from trusted chemical partners will remain a critical factor for success in the colorant business.
