1DescriptionWhite, odorless, crystalline powder, slightly hygroscopic.White, odorless, crystalline or granular powder or flakes, slightly hygroscopic.
2SolubilityPassesfreely soluble in water, sparingly soluble in ethanol (90% v/v).
3Identification (Reaction (b) for BenzoateCompliesA white sublimate should deposite on the inner wall of the tube.
4Identification (Reaction (c) for Benzoate )122°CMelting point should be 120°C to 124°C after crystallization
5Identification (Reaction (a) for Sodium)CompliesA dense white precipitate should form
6Identification (By IR)CompliesIR spectra of the sample should be concomitant with IR spectra of the standard
7Identification (By Chromatography)CompliesThe retention time of the major peak of the sample solution should correspond to that of the standard solution as obtained in the Assay
8Appearance of solutionPassesSolution should be clear and not more intensely colored than reference solution Y6.
