CAS No.: 52-51-7      Molecular Formula: C3H6BrNO4 Molecular Weight: 199.99 Synomas: 2-Bromo-2-Nitro-1, 3-Propanediol, Bronopol, BNP 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 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 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. Specifications: Characteristics: White or almost white crystalline powder Identification: A: Ir Positive Melting Point: 123-131º C Acidity(1%W/V): PH5.0-7.0 Related Substances: GC Loss On Drying: 0.5%max Sulphated Ash: 0.1%min Granular: 20mesh: 90% Pass 10mesh: 95% Pass Assay: 99.0% - 101.0% Other specs the same as BP2000 Usage: 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.
