Description

Chlorine CAS NO 22537-15-1 is a fundamental industrial chemical and a powerful oxidizing agent in its gaseous state. It is critical for water purification, sanitation, and as a key building block in the synthesis of a vast array of chemical products. This essential commodity is required by manufacturers in the water treatment, pharmaceutical, agrochemical, and plastics industries for its potent disinfectant and reactive properties.

Application

• Water Treatment & Disinfection: Primary use for municipal drinking water and wastewater treatment to eliminate pathogens and control microbial growth.
• Chemical Synthesis: Essential reagent in the production of chlorinated compounds, including polyvinyl chloride (PVC), solvents (e.g., methylene chloride, chloroform), and intermediates for pharmaceuticals and agrochemicals.
• Pulp & Paper Bleaching: Used in the bleaching process of wood pulp to produce white paper products.
• Sanitization & Hygiene: Employed in the formulation of industrial and institutional disinfectants, cleaners, and sanitizing solutions.
• Metallurgy: Used in the extraction and refining of certain metals, such as titanium and magnesium.
• Production of Inorganic Chemicals: Key raw material for manufacturing hydrochloric acid, sodium hypochlorite (bleach), and metal chlorides.

Quality Control

Our industrial-grade chlorine is produced and handled under stringent quality management protocols to ensure consistent purity and reliable performance for your processes. While specifications vary by application and delivery method (cylinders, ton containers, bulk), we guarantee compliance with relevant industry and safety standards. A Certificate of Analysis (COA) detailing key parameters such as purity and impurity levels is provided with every shipment.

Storage

Chlorine gas must be stored in approved, dedicated pressure vessels (cylinders or ton containers) in a cool, dry, well-ventilated area, away from direct sunlight and heat sources. Storage areas must be segregated from incompatible materials such as flammable substances, reducing agents, ammonia, and hydrocarbons. Containers must be kept tightly closed and upright, with valve protection caps secured when not in use. Local and national regulations for hazardous material storage must be strictly followed.
