Abstract A GC method was used in the determination of the enantiopurity of (±)-1-trimethylsilylethanol. The results showed the mean standand divergence and the average coefficient of variations were 9.948×10-4 and 0.198% respectively. This method was simple and highly efficient, selective and sensitive.
