| Description: | A clear, oily liquid, colourless or very slightly yellow. |
| Solubility: | Practically insoluble in water. Miscible with alcohol, ether and with ethanol (96%). |
| Identification A ( By Relative density, 20°C): | 1.043-1.048 |
| Identification B (By Refractive index, 20±0.5°C): | 1.490-1.495 |
| Identification C (By IR): | IR spectra of the sample should be concomitant with IR spectra of the standard. |
| Identification D (By TLC): | The principal spot in the chromatogram obtained with the test solution is similar in position and size to the principal spot in the chromatogram obtained with the reference solution. |
| Identification E (By Chemical test): | The solution becomes yellow or brownish-yellow and shows a green fluorescence. |
| Appearance of Solution: | The substance to be examined is clear and not more intensely coloured than reference solution Y6. |
