Description

2,3-Dihydroxypropanesulphonic Acid is a versatile organosulfur compound featuring both hydroxyl and sulfonic acid functional groups. This unique structure makes it a valuable intermediate and functional additive, particularly prized for its chelating and hydrophilic properties. It is essential for manufacturers in the pharmaceutical, personal care, and specialty chemical industries seeking to enhance product stability and performance.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs) and prodrugs, particularly where enhanced water solubility is required.
• Personal Care & Cosmetics: Acts as a humectant and skin-conditioning agent in formulations such as lotions, creams, and serums.
• Metal Chelation & Surface Treatment: Serves as a chelating agent in electroplating baths, metal cleaning solutions, and as a component in corrosion inhibitors.
• Biochemical Research: Employed as a buffer component or a modifying agent in biochemical assays and protein studies.
• Detergent & Cleaning Formulations: Functions as a builder and sequestering agent to improve the efficacy of cleaning products in hard water.
• Polymer & Resin Modification: Used to introduce sulfonate groups into polymers to improve hydrophilicity and ion-exchange capacity.

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). This product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which can lead to caking or degradation.
