Specification :

2-BROMO-2-NITRO-1,3-PROPANEDIOL (BRONOPOL)
CAS No.:  52-51-7
Molecular Formula:  C3H6BrNO4                    Molecular weight:  199.99
Structural Formula:

Properties:
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¡ãC. However due to its polymorphic characteristics, Bronopol undergoes a lattice rearrangement at 100 to 105¡ãC and this can often be wrongly interpreted as the melting point.
At temperatures above 140¡ãC 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.
