| Specifications | |
|---|---|
| Description: | Colourless or yellowish to brownish-yellow or pinkish, highly refrective liquid, becoming darker with age and on exposure to light. |
| Solubility: | Sparingly soluble in water, usually forming a cloudy solution; dissolves in solutions of fixed alkali hydroxides. Miscible with alcohol, with ether, with glycerine,with ethanol (96%) and with methylene chloride. |
| Identification A (By IR): | IR spectra of the sample should be concomitant with IR spectra of the corresponding standard |
| Identification B (By GC Chromatogram): | The retention time of the major peak of the sample solution corresponds to that of the standard solution, as obtained in the assay. |
| Relative density: | About 1.03 |
| Melting point: | About 11 °C |
| Boiling point: | About 202 °C |
| Appearance of Solution: | Freshly prepared solution should not more opalescent than reference suspension III and not more intensely coloured than reference solution BY7. |
