Description

2-Oxo-3-Sulfo-Propanoic Acid is a versatile sulfonated keto acid derivative, valued for its unique bifunctional reactivity as both a keto acid and a sulfonic acid. This compound serves as a critical high-purity intermediate in the synthesis of advanced pharmaceuticals, fine chemicals, and specialty surfactants. It is essential for manufacturers in the pharmaceutical, agrochemical, and specialty polymer industries seeking to introduce sulfonate groups or create complex molecular architectures.

Application

• Pharmaceutical Intermediate: Key building block for synthesizing active pharmaceutical ingredients (APIs), particularly those requiring sulfonate functionality for enhanced solubility or biological activity.
• Fine Chemical Synthesis: Used in the production of complex organic molecules, dyes, and photographic chemicals where its reactive keto and sulfo groups enable selective transformations.
• Bioconjugation & Cross-linking Agent: Employed in biochemical research and diagnostic reagent manufacturing for modifying proteins, peptides, and other biomolecules.
• Surfactant & Detergent Precursor: Acts as a starting material for the synthesis of anionic surfactants with high water solubility and stability.
• Polymer Modification: Used to introduce hydrophilic sulfonate groups into polymers, improving their water solubility, dyeability, or antistatic properties.
• Catalyst & Ligand Synthesis: Serves as a precursor for creating specialized ligands and catalysts used in asymmetric synthesis and industrial catalysis.

Quality Control

Our 2-Oxo-3-Sulfo-Propanoic Acid is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets exacting standards for use in sensitive applications. A Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and consistency.

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 performance.
