Description

Chlorine Dioxide is a potent oxidizing agent and disinfectant with the CAS number 10049-04-4. It is valued for its exceptional biocidal efficacy against a broad spectrum of microorganisms, including bacteria, viruses, and spores, without forming significant harmful by-products like trihalomethanes. This makes it a critical chemical for industries requiring high-level disinfection and process control, such as water treatment, food & beverage processing, and pulp bleaching.

Application

• Water Treatment & Disinfection: Primary disinfectant for municipal drinking water, wastewater, and industrial cooling towers.
• Food & Beverage Industry: Sanitizer for process water, equipment surfaces, and fruit/vegetable washing to control pathogens and extend shelf life.
• Pulp & Paper Manufacturing: Key bleaching agent (ECF - Elemental Chlorine Free) for producing high-brightness, high-strength pulp.
• Healthcare & Institutional: Disinfection of medical equipment, hard surfaces, and for biohazard decontamination.
• Oil & Gas Industry: Used for bacterial control (souring, biofilm) in water injection systems and hydraulic fracturing operations.
• Industrial Odor Control: Effective neutralizer for hydrogen sulfide and other malodorous compounds in air scrubbing systems.

Quality Control

Our Chlorine Dioxide is manufactured and handled under strict quality protocols to ensure consistency and performance. We adhere to relevant guidelines for its application in water treatment and industrial processes. A comprehensive Certificate of Analysis (COA), detailing purity, concentration, and key impurity profiles, is provided with each shipment to guarantee supply reliability and specification compliance.

Storage

Due to its highly volatile and easily oxidized nature, Chlorine Dioxide is typically generated on-site for immediate use and is not stored in bulk. For stabilized solutions or precursor chemicals, preserve in a tightly closed container, protected from light, and store in a cool, well-ventilated area away from heat, sparks, and incompatible materials such as strong acids and organic solvents. Specific storage instructions are provided with the material safety data sheet (MSDS).
