A simple and reliable Gas chromatography-Mass spectrometer method was developed for the
determination of Benzyl alcohol in injectable suspension. Methanol was used for extraction
solvent and co-extractive was removed by filtrated through anhydrous sodium sulfate. The
method was validated by determining parameters such as, specificity, linearity, limit of detection,
limit of quantitation, precision, recovery and robustness. The method was found to be specific
against matrix interferences. Linearity was evaluated over the concentration ranges of 0.1 μg/ml
to 10 μg/ml and correlation coefficient was more than 0.999. Both the inter day and intra day
precision of the system and method were determined. Recovery data obtained by fortifying three
matrices at 0.5 μg/g, 1.0 μg/g and 2.0 μg/g with ranged between 98 to 105 % and the relative
standard deviation (RSD) was obtained below 5%. Limit of detection and quantitation of Benzyl
alcohol were 0.05 and 0.1 μg/g.
