Chlorine (CAS 7782-50-5) is a greenish-yellow halogen gas and a high-volume industrial oxidant. It is used in water treatment and purification, in the bleaching of wood pulp and textiles, and as a feedstock in the manufacture of chlorinated hydrocarbons. It also serves as a disinfectant and biocide across municipal and industrial water systems.
Frequently Asked Questions
What is chlorine used for?
Chlorine is a high-volume industrial oxidant used in water treatment and purification, in the bleaching of wood pulp and textiles, and as a feedstock for chlorinated hydrocarbons. It also serves as a disinfectant and biocide across municipal and industrial water systems. RawSource supplies it for industrial use.
Where is chlorine found / how is it produced?
Chlorine (Cl2) is a greenish-yellow halogen gas produced industrially by the electrolysis of brine (chlor-alkali process), which co-produces caustic soda and hydrogen. It is supplied as a liquefied compressed gas. The CAS is 7782-50-5.
What is the UN/DOT classification for shipping chlorine?
Chlorine ships under UN 1017 (Chlorine), a Division 2.3 toxic gas with subsidiary hazards. It requires authorized pressurized containers, placarding, and trained handling. Review the SDS and applicable transport regulations before ordering; RawSource ships with compliant documentation and labeling.
What is the chemical formula and HS code for chlorine?
The molecular formula is Cl2 and the CAS is 7782-50-5; it is typically classified under HS 280110. Confirm the correct tariff classification with your customs broker for your destination. RawSource includes HS references on shipping documentation.
What bulk packaging is industrial chlorine available in?
As a liquefied compressed gas, chlorine is supplied in approved cylinders, ton containers, or larger bulk systems subject to regulatory and handling requirements. An SDS accompanies each shipment. Submit a bulk RFQ with your volume and delivery requirements for a current quote.
