Also known as N-Phenyl Peri Acid or 8-Anilino-1-naphthalenesulfonic acid, this organic intermediate is primarily used in the synthesis of acid dyes, azo dyes, sulfur dyes and specialty colorants. Its aromatic naphthalene structure and sulfonic acid functionality make it useful in controlled dye-manufacturing reactions.

USA manufacturers can source Phenyl Peri Acid for laboratory evaluation, formulation development, commercial dye production and recurring industrial requirements. Share the required quantity, specification and delivery destination to receive availability and a commercial quotation.

Phenyl Peri Acid Product Overview

Phenyl Peri Acid is an aromatic sulfonic acid derivative commonly supplied as a solid or powder. It serves mainly as an intermediate rather than as a finished dye. Dye manufacturers use it as a building block to develop colorants with the required shade, solubility and application performance.

The product is associated with the chemical name 8-anilino-1-naphthalenesulfonic acid and CAS number 82-76-8. Published chemical references list the molecular formula as C₁₆H₁₃NO₃S and the molecular weight as approximately 299.34 g/mol.

Buyers should confirm the exact identity, purity, moisture level and physical specifications through the supplied Certificate of Analysis and product specification before approving the material for commercial production.

Applications of Phenyl Peri Acid

Acid Dye Manufacturing

Phenyl Peri Acid is used as an intermediate in the manufacture of selected acid dyes. These dyes are commonly developed for applications where water solubility, controlled shade development and affinity for specific substrates are required.

Potential end-use sectors include:

• Wool textile dyeing
• Silk coloration
• Nylon dyeing
• Leather finishing
• Specialty textile coloration
• Industrial color formulations

The final dye performance depends on the complete synthesis route, coupling components and processing conditions.

Azo Dye Production

Phenyl Peri Acid may be used in reactions involved in producing azo-based colorants. Azo dyes contain one or more azo linkages and represent an important class of industrial dyes.

In dye synthesis, the material may contribute to:

• Shade development
• Aromatic structure formation
• Solubility characteristics
• Molecular weight adjustment
• Dye-substrate interaction

Manufacturers should validate the reaction route, purity requirement and downstream processing before scaling production.

Sulfur and Specialty Dyes

Published industry references also associate Phenyl Peri Acid with the production of sulfur dyes and selected specialty dye systems. It has been listed for dyes such as weak acid black and weak acid dark-blue products.

The product may be evaluated for:

• Dark-shade dye formulations
• Black dye intermediates
• Blue dye intermediates
• Specialty industrial colorants
• Custom dye-development projects

Suitability should be confirmed through laboratory trials because performance depends on the selected synthesis chemistry.

Textile Colorants

Textile dye producers use specialized intermediates such as Phenyl Peri Acid to manufacture colorants for different fibers and processing systems.

Potential textile sectors include:

• Wool processing
• Nylon fabrics
• Silk textiles
• Blended fabrics
• Industrial textile products
• Specialty finishing operations

The intermediate itself is not normally applied directly to fabric. It is converted through chemical synthesis into a finished dye or colorant.

Leather Dye Applications

Phenyl Peri Acid may be used in the production of dye intermediates intended for leather-coloring systems. Leather dyes require controlled penetration, shade uniformity and compatibility with finishing chemicals.

The final colorant may be used in:

• Footwear leather
• Upholstery leather
• Garment leather
• Bags and accessories
• Automotive leather
• Specialty finished leather

Manufacturers should assess the finished dye according to the leather type and processing method.

Paper and Industrial Colorants

Selected derivatives may also be considered for colorants used in paper and specialty industrial applications. Industry sourcing references identify Phenyl Peri Acid as an intermediate for colorants serving textile, leather and paper sectors.

Potential applications include:

• Colored paper
• Packaging paper
• Specialty paper products
• Industrial inks
• Laboratory colorants
• Custom chemical synthesis
