 Product Description

P.R.226, known as Pyranthrone, is a synthetic dye intermediate that belongs to the xanthene family. It is utilized in the production of various types of dyes, including fluorescent brightening agents and reactive dyes. Pyranthrone's chemical structure enables it to participate in specific chemical reactions necessary for dye synthesis, making it an essential component in the manufacturing process of colored materials. Its importance lies in its contribution to the brightness and intensity of dyes, affecting the quality and appearance of dyed goods.

 

Application

In practical applications, P.R.226 (Pyranthrone) is used in the textile industry for producing bright and vividly colored fabrics. Its role in the creation of fluorescent brightening agents ensures that paper and other materials retain their whiteness even after exposure to light. Additionally, pyranthrone-based reactive dyes are employed in the dyeing of cellulose fibers, offering excellent wash-fastness and color retention.
