| Specifications | |
|---|---|
| Description: | Colorless or yellowish to brownish-yellow or pinkish, highly refractive liquid, becoming darker with age and on exposure to light. A saturated solution of it is neutral or only slightly acid to litmus (USP/Ph.Eur) |
| 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 (USP / Ph.Eur) |
| Identification A (By IR): | IR spectra of the sample should be concomitant with IR spectra of the corresponding stanard (USP/Ph.Eur) |
| 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 (USP) |
| Relative density: | About 1.03 (Ph.Eur) |
| Melting point: | About 11°C (Ph.Eur) |
| Boiling point: | About 202°C (Ph.Eur) |
| Appearance of solution: | Freshly prepared solution should not more opalescent than reference suspension III and not more intensely colored than reference solution BY7 (Ph.Eur) |
| Assay (By GC): | 98.0%-102.0% (USP) |
| Organic Impurities / Related substances (Orthocresol): | Not more than 0.5% (USP/Ph.Eur) |
| Organic Impurities / Related substances (Paracresol): | Not more than 0.5% (USP/Ph.Eur) |
| Organic Impurities/ Related substances (Any unspecified impurity): | Not more than 0.1% (USP/Ph.Eur) |
| Organic Impurities / Related substances (Total impurities): | Not more than 1.0% (USP/Ph.Eur) |
| Clarity of Solution A (By Chemical Test): | A clear solution (USP) |
| Clarity of Solution B (By Chemical Test): | A clear solution (USP) |
| Acidity: | Not more than 0.5ml of 0.01 M sodium hydroxide should require to change the colour of the indicator to yellow (Ph.Eur) |
| Residue on evaporation: | 0.1% max (Ph.Eur) |
| Bacterial endotoxins: | 0.5 EU/mg (In-house) |
