Description: | Colourless or yellowish to brownish-yellow or pinkish, highly refrective liquid, becoming darker with age and on exposure to light. A saturated solution of it is neutral or slightly acid to litmus. |
Solubility: | Sparingly soluble in water, usually forming a cloudy solution; dissolves in solutions of fixed alkali hydroxides. Miscible with alcohol, with ether with glycerin, 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 |
Assay (By GC): | 98.0% - 102.0% |
Organic Impurities / Related substances (Orthocresol): | NMT 0.5% |
Organic Impurities / Related substances (Paracresol): | NMT 0.5% |
Organic Impurities/ Related substances (Any unspecified impurity): | NMT 0.1% |
Organic Impurities / Related substances (Total impurities): | NMT 1.0% |
Clarity of Solution A (By Chemical Test): | A clear solution |
Clarity of Solution B (By Chemical Test): | A clear solution |
Acidity: | Not more than 0.5ml of 0.01 M sodium hydroxide should require to change the colour of the indicator to yellow. |
Residue on evaporation: | NMT 0.1% |
