CAS 7681-52-9
Sodium Hypochlorite
Sodium Hypochlorite is a liquid chlorine disinfectant and bleach, supplied at 10–12% available chlorine for water disinfection, sanitation and textile bleaching.
Sodium hypochlorite (NaOCl) delivers chlorine in liquid form, without the hazards of handling chlorine gas. In water it forms hypochlorous acid, the active species that kills bacteria and viruses and oxidises iron, manganese, sulphide and organic colour. It is the simplest way to add a disinfectant residual to drinking water and to sanitise effluent before discharge.
Hypochlorite is inherently unstable: it loses strength over time, and faster with heat, sunlight and metal contamination. Product is made with a small excess of caustic soda to slow decomposition, and the available chlorine is measured at dispatch. For long transit routes or hot climates, calcium hypochlorite is often the more practical choice.

Sodium Hypochlorite — frequently asked
Sodium hypochlorite loses available chlorine steadily, faster at higher temperature and concentration and in sunlight. Stored cool and dark, it is best used within one to three months of manufacture. Available chlorine is measured at dispatch so buyers can plan dosing.
Yes. Hypochlorite solution ships as UN 1791, Class 8 (corrosive), in vented packaging that lets the oxygen released by decomposition escape safely.
Sodium hypochlorite is easiest to dose as a liquid and suits plants near the point of manufacture. Calcium hypochlorite carries six times more chlorine per kilogram and is much more stable in storage, so it is usually preferred for long export routes, remote sites and hot climates.
Yes. Chemtrade manufactures and exports Sodium Hypochlorite (CAS 7681-52-9) from Surat, Gujarat, India to more than 55 countries, for customers in Water Treatment. Send your grade, quantity and destination port for a quotation within one business day.
