Abstract

Background

Azithromycin (AZT), an antimicrobial, despite having a monograph in official compendiums and some methods available in the literature, there is still a demand for eco-efficient methods, which include green analytical chemistry.

Objectives

This study aimed to develop and validate a green spectrophotometric method for quantifying AZT tablets.

Methods

Purified water and ethanol (90:10, v/v) and sulfuric acid 20% as a diluent and reagent, respectively, quartz cubette and 482 nm were used. The Eco-Scale Assessment (ESA) tool was used to evaluate the greenness of the proposed analytical method.

Results

The proposed method was linear (20-70 µg mL-1 with a correlation coefficient of 0.9984), precise (RSD < 5%), selective by sample adjuvants, exact (100.46%), and robust against changes in acid proportion and wavelength. The ESA calculation was 85 points.

Conclusion

The proposed method can be classified as an excellent green alternative to quantify AZT in tablets, in accordance with ESA.
