Usage and cautions: 1. In water treatment applications, dilute it into a 1.5% aqueous solution first. Add the solution at a quantity of 80 to 100 ppm for one or two times each week depending on the multiplication of microorganisms like bacteria and algae. 2. Avoid direct eyes contact with it for a long period. Once the contact happens, rinse eyes with water without delay. No long-term contact with the skin is allowed. 3. Any contact with reducible metals is forbidden during storage, for example, iron and aluminum, so as to avoid decomposition. 4. Not suitable for use in the alkaline medium of ph> 9.0 due to its poor stability. Any combination of this chemical with highly nucleophilic chemicals, like s2- and r-nh2, will lead to declined quality or even complete failure of the product. Packaging: 250 kg per ibc drum or 250 kg per drum

Property: Appearance: Bronopol is supplied as crystals or crystalline powder, which may vary from white to pale yellow in colour depending on the grade of material being offered. Melting point: As a pure material, Bronopol has a melting point of about 130¦C. However due to its polymorphic characteristics, Bronopol undergoes a lattice rearrangement at 100 to 105¦C and this can often be wrongly interpreted as the melting point. At temperatures above 140¦C Bronopol will decompose exothermically releasing Hydrogen bromide and oxides of Nitrogen. Solubility: Bronopol is readily soluble in water although the dissolution process is endothermic. Solutions containing up to 28% w/v are possible at ambient temperature. Bronopol is poorly soluble in non-polar solvents but shows a high affinity for polar organic solvents.
