Description

Bis[(2-Hydroxyethyl)Ammonium] Sulphite is an organosulfur compound that serves as a versatile reducing agent and stabilizer in various industrial processes. Its primary value lies in its ability to act as an oxygen scavenger and antioxidant, protecting sensitive materials from oxidative degradation. This makes it a critical component for manufacturers in the polymer, textile, and photographic chemical industries seeking to enhance product shelf life and performance stability.

Application

• As a polymerization inhibitor and stabilizer in the production of synthetic resins and monomers like acrylates and styrene.
• As an antioxidant and reducing agent in photographic developer solutions to prevent fogging and maintain consistent image quality.
• As a scavenger for dissolved oxygen in boiler water treatment and other industrial water systems to prevent corrosion.
• In the textile industry as an agent in dyeing and printing processes to improve color fastness.
• As a chemical intermediate for the synthesis of other sulfonated or sulfur-containing specialty chemicals.
• In cosmetic formulations as an antioxidant to preserve the integrity of active ingredients.
• For research and development purposes in organic synthesis and material science.

Quality Control

Our Bis[(2-Hydroxyethyl)Ammonium] Sulphite is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure it meets precise specifications for purity, identity, and performance. A comprehensive Certificate of Analysis (COA) detailing assay, impurity profile, and physical characteristics is provided with each shipment to guarantee traceability and compliance with your quality requirements.

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 and easily oxidized nature, the container must be kept tightly sealed after opening to minimize exposure to moisture and air. For long-term storage, consider using an inert atmosphere.
