Description

2,3-Dibromo-1-propanesulfonic Acid Sodium Salt is a versatile organosulfur compound primarily used as a key intermediate in organic synthesis and specialty chemical manufacturing. Its value lies in its reactive dibromo and sulfonate functional groups, which enable its use in cross-coupling reactions, polymer modification, and as a precursor for surfactants and pharmaceutical agents. This chemical is essential for R&D laboratories and production facilities in the pharmaceutical, agrochemical, and material science industries seeking to introduce sulfonate moieties or bromine atoms into complex molecules.

Application

• Pharmaceutical Intermediate: Serves as a crucial building block in the synthesis of active pharmaceutical ingredients (APIs), particularly those requiring sulfonate groups for enhanced solubility or biological activity.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and plant growth regulators where the dibromo-sulfonate structure acts as a reactive handle.
• Polymer & Material Science: Functions as a monomer or cross-linking agent for creating specialty polymers, ion-exchange resins, and flame-retardant materials.
• Bioconjugation & Protein Modification: Employed in biochemical research for modifying proteins, peptides, and other biomolecules due to its electrophilic bromine atoms.
• Surfactant & Detergent Precursor: Acts as a starting material for the synthesis of anionic surfactants with specific branching and properties.
• Organic Synthesis Reagent: Utilized in various organic transformations, including nucleophilic substitution and cyclization reactions, to construct complex molecular architectures.

Quality Control

Our 2,3-Dibromo-1-propanesulfonic Acid Sodium Salt is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise specifications for synthetic applications. Certificates of Analysis (COA) documenting batch-specific results are available upon request, providing full traceability and compliance data for your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed to prevent absorption of atmospheric moisture. Keep away from incompatible materials such as strong oxidizing agents.
