ABSTRACT
OBJECTIVE:
To establish a method for the determination of related substances in anastrozole.METHODS:
HPLC was performed on the column of Welch Materials XB C18 with mobile phase of acetonitrile-water(3565,V/V)at a flow rate of 1.0 mL/min,detection wavelength was 210 nm,column temperature of 25 ℃,and the injection volume was 20 μL.RESULTS:
Only one impurity(impurity A)was detected in anastrozole,the linear range was 0.1-1.6 μg/mL(r=0.9996);limit of quantitation was 0.1 μg/mL,limit of detection was 0.02 μg/mL;RSDs of precision,stability and reproducibility tests were lower than 2%;recovery was 98.95%-105.29%(RSD%=1.78%,n=9).CONCLUSIONS:
The method is simple,accurate,and can be used for the determination of related substances in anastrozole.
