Characters A White to Creamy white, Crystalline powder, Odourless or almost odourless, Practically insoluble in water, Freely soluble in Ethanol (96%) and in ether. It dissolves in solutions of alkali. 3. 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. 4. 5.
