3-Hydroxy-2-naphthoyl-ortho-phenetidide

Product Overview

3-Hydroxy-2-naphthoyl-ortho-phenetidide, commonly known in the industry as Naphtol AS-PH, represents a critical coupling component within the azo dye and organic pigment manufacturing sectors. This specialized chemical intermediate is engineered to deliver exceptional color strength and stability when reacted with various diazonium salts. Our production process ensures a high level of molecular integrity, making it an ideal choice for manufacturers seeking consistent performance in downstream applications.

The compound features a distinct naphthalene backbone substituted with hydroxy and ethoxy groups, which significantly influences its solubility profile and reactivity during the coupling process. This structural configuration allows for the creation of vibrant red to violet shades, depending on the specific diazo component used. We prioritize rigorous quality control measures to maintain batch-to-batch consistency, ensuring that your production lines operate without interruption due to material variability.

Technical Specifications

Industrial Applications

The primary utility of this chemical lies in the synthesis of high-performance organic pigments. It serves as a foundational building block for producing azo pigments used in plastics, coatings, and printing inks. The resulting pigments exhibit excellent lightfastness and heat stability, which are crucial requirements for automotive coatings and industrial finishes. Furthermore, this intermediate is extensively utilized in the textile industry for the dyeing of cellulosic fibers such as cotton and viscose.

When applied in textile dyeing processes, 3-Hydroxy-2-naphthoyl-ortho-phenetidide provides deep, rich shades with superior wash fastness. The ethoxy substitution enhances the affinity of the dye molecule to the fiber matrix, ensuring long-lasting color retention even after repeated laundering. Manufacturers benefit from its reliable coupling efficiency, which minimizes waste and optimizes resource utilization during large-scale production runs.
