Description
Sodium Hypochlorite 12.5% Solution
Sodium Hypochlorite 12.5% Solution (CAS 7681-52-9, molecular formula NaOCl) is a treatment chemical specified by municipal and industrial plant operators where dose consistency and impurity control directly affect finished water quality. China Chemicals supplies it at 12.5% available chlorine in pack sizes from 1 L through to 200 L Drum, so laboratory trial quantities and full production volumes can be sourced from the same specification.
It is also traded as Bleach, Liquid Chlorine, Hypo. Every consignment ships with a batch-specific Certificate of Analysis and the current Safety Data Sheet, and material is stored and picked under stock rotation so you receive product well inside its shelf life.
