In the intricate world of chemical manufacturing, certain compounds stand out for their fundamental importance. 2-Aminonaphthalene-1-sulfonic acid, commonly known by its CAS number 81-16-3, is precisely one such critical component. This versatile chemical serves as a cornerstone intermediate, particularly in the production of a wide spectrum of azo dyes and pigments that color our world, from textiles to coatings. Understanding its properties and applications is key for procurement managers and R&D scientists seeking high-quality materials for their formulation needs.

As a primary building block, 2-Aminonaphthalene-1-sulfonic acid's unique molecular structure, featuring both an amino and a sulfonic acid group on a naphthalene core, allows for diverse chemical reactions. This reactivity is leveraged extensively in the synthesis of complex dye molecules. For instance, it is instrumental in the production of well-known dye intermediates like J acid and gamma acid, which in turn are used to create vibrant shades for the textile industry. Furthermore, its role extends to the manufacturing of specific reactive dyes, such as reactive red K-1613, contributing to the bright and durable colors seen in fashion and home textiles.

The demand for high-purity intermediates like 2-Aminonaphthalene-1-sulfonic acid cannot be overstated. Impurities can significantly affect the final color yield, hue, and fastness properties of the dyes and pigments produced. Therefore, procurement professionals often seek suppliers who can guarantee consistent quality and assay values, typically above 99.0%. When looking to buy 2-aminonaphthalene-1-sulfonic acid, it is crucial to partner with a reputable manufacturer in China or a trusted supplier who adheres to international standards like USP, BP, and EP.

The benefits of securing a reliable supply of this chemical intermediate are manifold. A consistent supply chain ensures uninterrupted production cycles, while competitive pricing from a direct manufacturer can significantly impact the cost-effectiveness of the final product. For companies looking to optimize their sourcing, exploring options from established chemical suppliers who offer online purchase support and readily available technical data (like TDS and SDS) is a strategic move. If your R&D team is exploring new pigment formulations or seeking to enhance existing textile dye ranges, securing high-quality 2-Aminonaphthalene-1-sulfonic acid is a critical first step. Consider reaching out to a trusted 2-aminonaphthalene-1-sulfonic acid supplier for detailed product information and a competitive price quote to meet your specific project requirements.
