2-Bromo-2-Nitro-1, 3-Propanediol (Bronopol)
CAS No.: 52-51-7 Molecular Formula: C3H6BrNO4
Molecular Weight: 199.99
Structural Formula:
Property:
Appearance - 2-Bromo-2-Nitro-1, 3-Propanediol (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 130º C. However due to its polymorphic characteristics, Bronopol undergoes a lattice rearrangement at 100 to 105º C and this can often be wrongly interpreted as the melting point.
At temperatures above 140º C 2-Bromo-2-Nitro-1, 3-Propanediol (Bronopol) will decompose exothermically releasing Hydrogen bromide and oxides of Nitrogen.
Solubility - 2-Bromo-2-Nitro-1, 3-Propanediol (Bronopol) is readily soluble in water although the dissolution process is endothermic. Solutions containing up to 28% w/v are possible at ambient temperature.
2-Bromo-2-Nitro-1, 3-Propanediol (Bronopol) is poorly soluble in non-polar solvents but shows a high affinity for polar organic solvents.
