  Identification
   
 
  
A. The infrared absorptionSpecificationsto Creamy white, Crystalline powder, Odourless spectrum is concordant with reference spectrum Benzyl Hydroxybenzoate (RS 028)
   
B. The absorption appendix II B in the range 230 to 350 nm of a 0.001% w/v solution in ethanol (96%)
   
C. Dissolve 0.1 gm in 2 ml of ethanol (96%) boil and add 0.5 ml of nitric acid solution of mercury. A precipitate is produced slowly and the supermatant liquid becomes red.
   
D. Melting point about 112°C Appendix V A
 Acidity

Dissolve 0.2g in 10 ml ethanol (50%) previously neutralized to methyl red solution and titrate with 0.1 M sodium hydroxide VS using methyl red solution as indicator. Not more than 0.1 ml of 0.1 M Sodium hydroxide VS is required to change the colour of the solution.
