|---|---|
| Appearance: | Clear, colourless or slightly yellowish liquid. |
| Solubility: | Miscible with water and with ethanol (96%). It froths copiously when shaken. |
| Identification A (By UV spectrophotometry): | Absorbance maxima should be at 257 nm, 263 nm and 269 nm. Shoulder about 250 nm |
| Identification B (By Liquid Chromatography): | The principal peaks in the chromatogram obtained with the test solution are similar in retention time to the principal peaks in the chromatogram obtained with the reference solution. |
| Identification C (By Chemical test): | The crystals should melt at 127°C to 133°C |
| Identification D (By Chemical test): | The methylene chloride layer should becomes blue. |
| Identification E (By Chemical test): | The precipitate should dissolves easily with the possible exception of a few large particles which dissolve slowly. |
| 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. |
