Description

Ammonium Sodium 2-[[5-Carbamoyl-1,6-Dihydro-2-Hydroxy-4-Methyl-6-Oxo-1-[2-(4-Sulphonatophenyl)Ethyl]-3-Pyridyl]Azo]-5-[(3-Phosphonophenyl)Azo]Benzenesulphonate is a high-purity, synthetic azo dye intermediate of significant industrial importance. Its complex molecular structure, featuring both sulphonate and phosphonate groups, provides excellent water solubility and chelating properties, making it a valuable precursor for specialized colorants. This compound is primarily sought after by manufacturers in the textile, ink, and specialty chemical sectors for producing high-performance dyes and functional pigments.

Application

• Textile Dye Intermediate: A key precursor for synthesizing reactive and direct dyes for cotton, wool, and nylon, offering enhanced color fastness and brightness.
• Inkjet Ink Formulation: Used in the production of high-quality, water-based pigment inks for commercial and industrial printing due to its excellent dispersion and stability.
• Functional Pigment Synthesis: Serves as a building block for creating pigments with specific properties for coatings, plastics, and security printing applications.
• Analytical Reagent: Potential use as a complexometric indicator or a chelating agent in specific laboratory and analytical chemistry procedures.
• Research & Development: Employed in chemical R&D for exploring new chromophores, metal-complex dyes, and advanced material science applications.

Quality Control

Every batch of our Ammonium Sodium Azo Dye Intermediate is manufactured under a strict quality management system. We perform comprehensive in-process and final release testing, including HPLC for purity and identity, spectrophotometric analysis for color strength, and stringent control of residual solvents and heavy metals. A detailed Certificate of Analysis (COA) confirming compliance with agreed specifications is provided with each shipment to ensure traceability and supply chain integrity for our global B2B clients.

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 sealed in a low-humidity environment to prevent product degradation and caking. Keep away from incompatible materials.
