2-Bromo-2-Nitropropane-1 3-Diol (Bronopol)
CAS No.:
52-51-7
Molecular Formula:
C3H6BrNO4
Molecular Weight:
199.99
Structure Formula:
Properties:
Bronopol (CAS 52 51 7) is supplied as crystals or crystalline powder, which may vary from white to pale yellow in color depending on the grade of material being offered.
As a pure material, this halogen product has a melting point of about 130℃. However, due to its polymorphic characteristics, 2-bromo-2-nitropropane-1 3-diol undergoes a lattice rearrangement at 100 to 105℃ and this can often be wrongly interpreted as the melting point.
At temperatures above 140℃, this kind of halogen will decompose exothermically releasing hydrogen bromide and oxides of nitrogen.
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 fungicide (CAS 52 51 7) is poorly soluble in non-polar solvents but shows a high affinity for polar organic solvents.
