Description

1,3,5-Naphthalenetrisulfonic Acid Trisodium Salt is a high-purity, water-soluble aromatic sulfonate salt valued for its strong anionic character and chelating properties. This compound serves as a critical intermediate and functional additive in advanced chemical synthesis and industrial formulations. It is essential for manufacturers in sectors requiring high-performance dispersants, dye intermediates, and specialized surfactants.

Application

• Dye and Pigment Intermediate: A key building block for synthesizing acid dyes, reactive dyes, and optical brighteners.
• High-Performance Dispersant: Used in the formulation of concrete admixtures, ceramic slurries, and pigment dispersions to prevent agglomeration.
• Chelating Agent: Effective in water treatment and textile processing for binding and sequestering polyvalent metal ions like calcium and magnesium.
• Surfactant and Detergent Builder: Functions as a hydrotrope and anionic component in specialty cleaning and industrial detergent formulations.
• Electroplating Additive: Employed in electroplating baths to improve bath stability and metal deposit quality.
• Pharmaceutical Intermediate: Used in the synthesis of certain pharmaceutical compounds and diagnostic agents.
• Research & Development: Serves as a standard or reagent in chemical research and analytical chemistry.

Quality Control

Our 1,3,5-Naphthalenetrisulfonic Acid Trisodium Salt is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, identity, and performance. A Certificate of Analysis (COA) documenting key parameters is provided with every shipment to guarantee traceability and compliance with your quality requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect quality and handling properties.
