Abstract 

A simple, rapid, and sensitive flow injection spectrophotometric system for
determination of tetracycline hydrochloride (TCH) in pharmaceutical
products. The method is based on diazotization of 2-aminopyridine and
subsequent coupling with tetracycline hydrochloride in alkaline medium. The
formed azo-dye showed maximum absorbance at 388 nm and the calibration
curve in the linear range of 25.0-150.0 µg/ml of tetracycline hydrochloride
with correlation coefficient 0.9988, while the detection limit was 10 µg/ml
and sample frequency 123 samples/hour. The accuracy and precision data for
determination of TCH by flow injection analysis method for triplicate injection
at three concentration levels(25, 80 and 150 µg/ml) the relative standard
deviation (RSD %) are 1.04, 0.247 and 1.75%, and relative error percent (E rel )
are -3.92, +1.06 and -1.9%. The proposed method was successfully applied to
the determination of tetracycline hydrochloride in pharmaceutical products.
The results obtained were in good agreement with those obtained by
reference method.

Key Words:
tetracycline hydrochloride, 2- aminopyridine, flow injection spectrophotometric
