2-Bromo-2-Nitro-1, 3-Propanediol (Bronopol)
CAS No.: 52-51-7
Molecular Formula: C3H6BrNO4Molecular Weight: 199.99
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
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.

As bactericide, Bronopol is widely used in industrial circulating water, algae-killing,
paper pulp, paint, plastic, timber-cooling circulating water and
other industries. In addition, Bronopol can be used to prevent daily-used cosmetic products from moldly
