| Specifications | |
|---|---|
| Appearance/Description: | White, or yellowish-white, crystalline solid, colorless crystals or white crystalline powder or lumps. |
| Solubility: | Freely soluble in alcohol (ethanol 96%), in chloroform, in ether and in vegetable oils. Practically insoluble in water & in propylene glycol,very soluble in acetone, ethyl acetate, N,N-dimethylformamide. |
| Identification (By IR): | IR spectra of the sample should be concomitant with IR spectra of standard. |
| Identification (by IR): | IR spectra of the sample should show absorption at the wavenumbers about 3610 cm-1, 1430 cm-1, 1230 cm-1, 1152 cm-1 and 865cm-1 . |
| Identification (By Chromatography): | The retention time of the BHT peak of the sample solution corresponds to that of the standard solution as obtained in the assay. The chromatographic profile of sample solution should exhibit only one major peak corresponding to the main compound. |
| Identification (By Freezing point): | 69°C - 70°C |
| Identification (By UV absorbance test): | The solution should show an absorption maximum at 278 nm & the specific absorbance at the maximum should between 80 to 90. |
| Identification (By chemical test 1): | A blue colour should develop. |
| Identification (By chemical test 2): | The liquid turns yellow as its melts, and then turns reddish brown. |
| Identification (By chemical test 3): | When small crystals of 2,2-bipyridyl are added, the liquid become red. |
