Description

1-Hydroxy-3-Phenyl-1,3-Propanedisulfonic Acid Disodium Salt is a high-purity, water-soluble organic sulfonate salt with versatile chelating and dispersing properties. This compound is valued for its ability to effectively sequester metal ions and stabilize formulations in demanding chemical environments. It is primarily utilized by manufacturers in the pharmaceutical, agrochemical, and specialty chemical synthesis industries.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs), particularly where sulfonate groups are required for solubility or biological activity.
• Agrochemical Formulations: Acts as a stabilizer, dispersing agent, or chelating agent in pesticides, herbicides, and fungicides to enhance efficacy and shelf-life.
• Catalyst and Ligand: Serves as a ligand in metal-catalyzed organic reactions or as a component in catalyst systems for fine chemical production.
• Dye and Pigment Industry: Functions as a dispersant and leveling agent in the production of dyes and organic pigments, improving color uniformity.
• Water Treatment Chemicals: Employed as a scale inhibitor and chelating agent in industrial water treatment processes to control metal ion precipitation.
• Research & Development: Used in chemical research as a building block for novel sulfonated compounds and in material science applications.

Quality Control

Our 1-Hydroxy-3-Phenyl-1,3-Propanedisulfonic Acid Disodium Salt is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets high-purity standards suitable for pharmaceutical and industrial applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment.

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 nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect product stability and handling properties.
