Chlorine

Chlorine (CAS 7782-50-5), commonly referenced as Cl2, is a high-demand industrial oxidizer and biocide used across large-scale manufacturing and municipal infrastructure.

It functions primarily as a bleaching agent and disinfectant, delivering broad-spectrum microbial control and chemical oxidation across continuous production processes.

In water treatment, Cl2 is dosed directly into municipal and industrial water systems to eliminate pathogens and control biofilm in distribution networks.

Pulp and paper producers use it to bleach cellulose fibers, achieving the brightness levels required for printing and packaging grades for various industrial sectors.

Textile and leather processors apply it to whiten natural fibers and prepare hides for dyeing by breaking down pigment structures during the manufacturing phase.

Pharmaceutical manufacturing relies on chlorine-based disinfection for cleanroom environments and process water sanitation where microbial limits are tightly regulated.

Chlorine is supplied as a liquefied compressed gas, typically in pressurized cylinders, ton containers, or bulk rail/road tankers depending on volume requirements.

Technical grade is the standard for industrial applications, with purity levels commonly specified at 99.5% or higher for most commercial and municipal buyers.
