HPLC Analysis of Tetramisole Enantiomers on Astec® CYCLOBOND® I 2000 DMP

HPLC Analysis of Tetramisole Enantiomers on Astec® CYCLOBOND® I 2000 DMP

Conditions

column Astec CYCLOBOND I 2000 DMP 25 cm x 4.6 mm I.D., 5 µm particles (20724AST)
column temp. 35 C
mobile phase (A) 100 mM ammonium acetate, pH 5 with acetic acid (B) acetonitrile, 80:20, v/v
flow rate 1.0 ml/min
sample 200 ug/mL tetramisole in mobile phase A:methanol, 80:20, v/v
injection 10 µl
detector UV, 230 nm

Description

Analysis Note Cocaine is often found laced with levamisole (one of the tetramisole enantiomers). These compounds are readily separated using the CYCLOBOND I 2000 DMP column - a derivatized cyclodextrin column only offered by Supelco. The method is also a suitable replacement for published methods utilizing CYCLOBOND I 2000 SN (no longer available) for the analysis of levamisole. A Cerilliant CRM was used to ensure reliable MS identification and quantification.
