CAS No.: 52-51-7
HS code: 2905320000
Molecular Formula: C3H6BrNO4
Molecular Weight： 199.99
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.
