Description

3-Hydroxypropanesulfonic Acid is a versatile organosulfonic acid derivative, valued for its bifunctional nature as both a sulfonic acid and an alcohol. This compound is a key intermediate and building block in the synthesis of specialized chemicals, offering excellent water solubility and reactivity. It is primarily sought by manufacturers in the pharmaceutical, biochemical research, and specialty chemical sectors for applications ranging from buffer systems to the production of advanced surfactants and zwitterions.

Application

• Pharmaceutical Intermediates: A crucial building block in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs, particularly those requiring sulfonate or hydroxyl functionality.
• Biochemical Buffers & Reagents: Used in the preparation of specialized biological buffers (e.g., CAPS, Good's buffers) and as a reagent in protein and enzyme studies.
• Surfactant & Detergent Synthesis: Serves as a precursor for manufacturing high-performance anionic and zwitterionic surfactants with enhanced solubility and stability.
• Electroplating Additives: Employed in electroplating baths as a brightening agent and stabilizer, particularly for nickel and other metal plating processes.
• Polymer Modification: Used to introduce sulfonate groups into polymers, enhancing properties like hydrophilicity, ion-exchange capacity, and anti-static characteristics.
• Chemical Research & Development: A valuable synthon in organic chemistry for constructing complex molecules, including ligands, catalysts, and functional materials.

Quality Control

Our 3-Hydroxypropanesulfonic Acid is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure it meets high-purity standards suitable for research and industrial synthesis. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting key parameters such as assay, identity, and impurity profiles. We can support compliance requirements for various applications, including those under cGMP guidelines where applicable.

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 tightly sealed after each use to prevent absorption of atmospheric moisture, which can affect product quality and stability.
