Product Description

CAS No.:                     52-51-7

HS code: 2905320000

Molecular Formula:  C3H6BrNO4

Molecular 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 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 so ents but shows a high affinity for polar organic so ents.



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


Package and Storage:

Packed by paper drum( 25KG/50KG) or as per customer requirement

Store it in cool, dry and ventilative places. Keep away from incompatible substance. It can not be stored together with food and feedstuff.
