Several organic compounds, viz., aliphatic, aromatic and chlorinated hydrocarbons, cyclicethers, alcohols, ketones and esters have been used as test solutes. Classification of the stationary phase according to McReynolds' method, Novak's thermodynamic approach and Snyder's selectivity triangle has been carried out. The results reveal that the stationary phase falls in the medium polar category Industrially important compounds with close boiling points are satisfactorily resolved on this stationary phase. Investigations on the stability of the stationary phase showed that it is stable upto 140°C.It is concluded that stearyl-1-<span style="font-size:11.0pt;line-height:115%; font-family:" dejavu="" sans","serif";mso-fareast-font-family:"dejavu="" sans";="" mso-bidi-font-family:"times="" new="" roman";mso-ansi-language:en-us;mso-fareast-language:="" en-us;mso-bidi-language:ar-sa"="">ά<span style="font-size:11.0pt; line-height:115%;font-family:" calibri","sans-serif";mso-fareast-font-family:="" "dejavu="" sans";mso-bidi-font-family:"times="" new="" roman";mso-ansi-language:en-us;="" mso-fareast-language:en-us;mso-bidi-language:ar-sa"="">-naphthyl acetate can be used as a versatile, easily available and cheap stationary phase for GLC.</span></span></span></span></span>
