The world of textiles and color is intricately linked to the chemical industry, and at the heart of vibrant hues lie essential intermediates. One such critical compound is 2-Amino-4,8-Naphthalenedisulfonic Acid, commonly known as Amino C Acid or Cassella Acid, identified by its CAS number 131-27-1. This naphthalene derivative plays an indispensable role in the synthesis of a wide array of dyes, particularly reactive and direct dyes, which are foundational to the global textile, paper, and leather industries. Understanding its properties and applications is key for procurement managers and R&D scientists seeking reliable raw materials.

As a leading manufacturer and supplier in China, we recognize the importance of consistent quality and availability for intermediates like 2-Amino-4,8-Naphthalenedisulfonic Acid. This chemical, appearing as a grey to light red powder, is meticulously produced to ensure a minimum content of 70%, a specification vital for achieving predictable and brilliant color outcomes in downstream applications. Its precise molecular structure allows for its effective use as a diazo component in creating complex dye molecules that offer excellent color fastness and vibrancy.

The primary applications of 2-Amino-4,8-Naphthalenedisulfonic Acid are in the production of specific dye types. It is a key precursor for producing popular reactive dyes such as reactive yellow and reactive brown. These dyes form covalent bonds with textile fibers, leading to exceptional washfastness and color stability. Furthermore, it is instrumental in synthesizing direct dyes, including the well-known direct fast blue B2BL. Direct dyes are applied directly to fibers like cotton and rayon, offering a cost-effective coloring solution. For those looking to purchase these vital dye intermediates, sourcing from reputable Chinese manufacturers ensures a stable supply chain and competitive pricing.

Beyond its established roles, the chemical industry's drive towards sustainability is also influencing the application of intermediates like Amino C Acid. There is a growing interest in 'green chemistry' preparation methods. This involves developing more environmentally friendly synthesis routes that minimize waste and reduce the use of hazardous substances. 2-Amino-4,8-Naphthalenedisulfonic Acid is being explored and utilized in these greener processes, demonstrating its adaptability to modern manufacturing demands. For companies aiming to enhance their environmental credentials and comply with stricter regulations, integrating intermediates suitable for green synthesis is becoming a strategic imperative.

Procurement managers and product formulators seeking to buy 2-Amino-4,8-Naphthalenedisulfonic Acid will find that partnering with experienced Chinese suppliers offers significant advantages. These include access to high-purity materials, bulk purchasing options with flexible packaging (such as 25KG drums), and assurance of consistent production capacity. The price for CAS 131-27-1 can vary based on purity and quantity, making it essential to request a quote from trusted manufacturers. By securing a reliable supply of this fundamental dye intermediate, businesses can ensure the quality and efficiency of their colorant production, contributing to both product excellence and a more sustainable future for the chemical industry.
