Description

3-Amino-1-Propanesulfonic Acid Sodium is the sodium salt of a sulfonic acid derivative of 1,3-diaminopropane, offering enhanced water solubility and stability. This compound serves as a versatile building block and intermediate in organic synthesis, particularly valuable for introducing sulfonate functionality. It is essential for manufacturers and R&D teams in the pharmaceutical, biochemical, and specialty chemical sectors seeking to develop new active compounds or functional materials.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs), particularly those requiring sulfonate or amino-sulfonate moieties for enhanced solubility or biological activity.
• Biochemical Research: Acts as a precursor or buffer component in biochemical assays and molecular biology applications.
• Ligand Synthesis: Serves as a key starting material for creating chelating agents and ligands used in catalysis and metal ion sequestration.
• Surface Modification Agent: Employed to modify surfaces or polymers by introducing hydrophilic sulfonate groups.
• Specialty Surfactant Precursor: Utilized in the development of novel amphoteric or anionic surfactants with specific performance characteristics.
• Cross-linking Agent: Potential use in the synthesis of polymers and resins where the amino and sulfonate groups can participate in cross-linking reactions.

Quality Control

We maintain a rigorous quality management system to ensure batch-to-batch consistency and high purity. Our products undergo comprehensive analytical testing, including HPLC, NMR, and titration methods, to verify identity, potency, and impurity profiles. A Certificate of Analysis (COA) detailing all test results is provided with each shipment and is available upon request.

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). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect product quality and handling.
