Description

Disodium 6-Acetamido-4-Hydroxy-3-[(3-Phosphonatophenyl)Azo]Naphthalene-2-Sulphonate is a high-purity, water-soluble azo dye intermediate characterized by its unique phosphonated aromatic structure. This compound matters for its critical role in synthesizing specialized dyes and pigments with enhanced color fastness and metal-complexing properties. It is primarily needed by manufacturers in the textile, ink, and specialty chemical industries seeking to develop advanced colorants for technical applications.

Application

• Key intermediate for the synthesis of azo dyes and pigments, particularly those requiring high light and wash fastness.
• Production of specialty textile dyes for nylon, wool, and silk, where its phosphonate group can improve fiber affinity.
• Manufacture of functional dyes for ink-jet printing and security ink applications.
• Precursor for metal-complex dyes used in automotive coatings and industrial paints.
• Research and development of novel chromophores in academic and industrial laboratories.
• Potential use in the formulation of analytical reagents and indicators due to its color-changing properties.

Quality Control

Our Disodium 6-Acetamido-4-Hydroxy-3-[(3-Phosphonatophenyl)Azo]Naphthalene-2-Sulphonate is produced under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise customer specifications and consistent performance. Certificates of Analysis (COA) documenting all critical parameters are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
