Bronopol or 2-Bromo-2-nitropropane-1,3-diol or 2-bromo-2-nitro-1,3-propanediol
Bronopol or 2-Bromo-2-nitropropane-1,3-diol or 2-bromo-2-nitro-1,3-propanediol is not found in USP monograph.
Specifications of Bronopol BP Ph Eur Grade:
C3H6BrNO4 --- 200.0 --- CAS 52-51-7
Action and use: Antibacterial preservative.
DEFINITION
Bronopol is 2-bromo-2-nitropropane-1,3-diol. It contains not less than 99.0% and not more than 101.0% of C3H6BrNO4, calculated with reference to the anhydrous substance.
CHARACTERISTICS
White or almost white crystals or crystalline powder.
Freely soluble in water and in ethanol (96%); slightly soluble in glycerol and in liquid paraffin.
IDENTIFICATION
A. The infrared absorption spectrum is concordant with the reference spectrum of bronopol.
B. Dissolve 0.1 g in 10 mL of water, add 10 mL of 7.5M sodium hydroxide and, carefully with constant stirring and cooling, 0.5 g of nickel-aluminium alloy. Allow the reaction to subside, filter and carefully neutralise with nitric acid. The resulting solution yields reaction A characteristic of bromides.
C. Melting point, after drying over phosphorus pentoxide at a pressure not exceeding 0.7 kPa, about 130C.
TESTS
Acidity or alkalinity: pH of a 1% w/v solution, 5.0 to 7.0.
Related substances: To pass the test.
Sulfated ash: Not more than 0.1%.
Water: Not more than 0.5% w/w.
