Application:	ß-DEX^™-325 column was used in gas-liquid chromatography (GLC), for determination of (R)-1-O-acetyl-2-ethyl-1,3-propanediol, formed from 2-Ethyl-1,3-propanediol 1 and its related di-O-acetate, by partial chemoenzymatic acetylation and deacetylation, by Pseudomonas fluorescens lipase. ß -Dex^™-325 capillary column was also used for resolving 8-acetoxylinalool enantiomers, in an experimental study done in order to study the origin of the enantioselectivity in the biosynthesis of the lilac compounds in Actinidia arguta flowers.
Chem/Phys Resistance:	Temp. Limits: • 30 °C to 230 °C
General description:	The chiral stationary phase in β-DEX 325 columns contains 2,3-di-O-methyl-6-0-TBDMS-β-cyclodextrin embedded in an intermediate polarity phase. The Supelco β-DEX 325 is similar in both chemistry and use to the CHIRALDEX B-DM phase, the main difference being the concentration of the dimethyl-derivatized cyclodextrin that is doped into the polysiloxane carrier.
