1DescriptionYellowish, highly, refractive liquid, becoming darker with age and on exposure to light. A saturated solution of it is neutral to litmus.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
2SolubilityPassesSparingly soluble in water, usually forming a cloudy solution; dissolves in solutions of fixed alkali hydroxides. Miscible with alcohol, with ether, and with glycerin.
3Identification A (By IR)CompliesIR spectra of the sample should be concomitant with IR spectra of the corresponding standard
4Identification B (By GC Chromatogram)CompliesThe retention time of the major peak of the sample solution corresponds to that of the standard solution, as obtained in the assay.
