The chlorine produced is available in cylinders sizes ranging from 450 g to 70 kg, as well as drums (865 kg), tank wagons (15 tonnes on roads; 27–90 tonnes by rail), and barges . Most of the chlorine produced is used for chemical processes involving the introduction of chlorine into organic compounds, yielding carbon tetrachloride (used as a solvent, a fire extinguisher, and a dry-cleaning agent), glycols (used as antifreeze), and other organic compounds for the manufacture of plastics (polyvinyl chloride), dyes, and synthetic rubber. Sulfur chloride, made by the action of chlorine on carbon disulfide or by combining sulfur and chlorine, is used in the vulcanization of rubber and as a chlorinating agent in organic synthesis. Sulfur dioxide combines with chlorine to give sulfuryl dioxide. Chlorine and carbon monoxide form carbonyl chloride (COCl₂), or phosgene, is used mainly in the preparation of isocyanates and polyurethanes and in metallurgy to transform certain oxides into chlorides.

Much chlorine is used to sterilize water and wastes, and the substance is employed either directly or indirectly as a bleaching agent for paper or textiles and as “bleaching powder” Chlorine is applied in the manufacturing of high-purity hydrochloric acid, the extraction of titanium with the formation of titanium tetrachloride (TiCl₄), and the removal of tin from old tinplate.
