Specifications  
Description: White, crystalline solid, having a faint, characteristic odor.
Solubility: Freely soluble in alcohol, in chloroform in ether and in vegetable oils.Insoluble in water & in propylene glycol very soluble in acetone
Identification (by IR): IR spectra of the sample should be concomitant with IR spectra of standard
Identification by chromatogram: The retention time of the BHT peak of the sample solution corrresponds 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: A blue colour should devlop
Appearance of Solution: The solution is clear and not more intensely coloured than reference solution Y5 to BY5.
