CAS No.: 52-51-7

Molecular Formula: C3H6BrNO4 Molecular Weight: 199.99

Structural Formula:



- 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℃. However due to its polymorphic characteristics, Bronopol undergoes a lattice rearrangement at 100 to 105℃ and this can often be wrongly interpreted as the melting point.

At temperatures above 140℃ 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.
