| Identification (By chemical test 1): | A white precipitate should form, and it should dissolve after adding 5ml of alcohol |
| Identification (By chemical test 2): | An orange-red color should produce. |
| Identification (By chemical test 3): | The crystals should melt at 127°C to 133°C |
| Identification (By chemical test 4): | The methylene chloride layer should become blue. |
| Identification (Chloride): | A solution should yield a white, curdy precipitate which should insoluble in nitric acid but soluble in slight excess of 6 N ammonium hydroxide |
| Identification (By UV spectrophotometry): | Absorbance maxima should be at 257 nm, 263 nm and 269 nm. Shoulder about 250 nm |
| Identification (By Liquid Chromatography): | The principal peaks in the chromatogram obtained with the test solution should be similar in retention time to the principal peaks in the chromatogram obtained with the reference solution |
| Appearance of solution: | Solution should be clear and not more intensely coloured than reference solution Y6 |
| Acidity or Alkalinity: | Not more than 0.1ml of 0.1M hydrochloric acid or 0.1M sodium hydroxide should require to change the colour of the indicator |
