Abstract Analytical chemistry research has shifted towards environmentally friendly substitutes that reduce waste and avoid hazardous substances. These efforts align with broader environmental goals inspire sustainable responsible science. The objective of this work is to develop validate an analytical method verify its greenness using specific tools, including GREEnness (AGREE), metric for sample preparation (AGREEprep), green procedure index, complex Eco-Scale, volume intensity, score, HPLC-EAT (Environmental Assessment Tool). Effective treatment chronic cough relies heavily on adequately utilizing salbutamol (SAL) guaifenesin (GUA) in the presence sodium benzoate (SOB) preservative. isocratic elution mode used Zorbax Eclipse Plus C18 column (15 cm × 4.6 mm, 3.5 µm). It could move 1.5 mL·min −1 , hold 50 µL, have a temperature 30°C, autosampler 5°C. detect UV light at 276 nm had mobile phase 80:20 v/v buffer solution acetonitrile. We successfully established highly accurate calibration curves three components SAL, GUA, SOB within optimal range 2–50 µg·mL . coefficient correlation ( r ) these was impressive 0.9999 SAL while it 0.9998 SOB. recovery values were 100.15%, 100.47%, 100.92% SOB, respectively. selectivity sensitivity ingredients confirmed according International Council Harmonisation guidelines, as no interference occurred from any components. implemented Six Sigma, resulting precision productivity.

Modern society is increasingly reliant on sustainable solutions. We suggest a creative study that meets the standards of sustainability in analytical chemistry. The objective to promote eco-friendly methods for concurrently detecting Gatifloxacin (GAT) and benzalkonium chloride (BEN) ocular Using sustained mobile phase flow rate 0.8 mL/min-1 acidic water: 10% 1-butanol water (40:60, v/v), GAT was retained 2.242 min at 287 nm, followed by BEN homologues 215 nm next 2.982 4.201 min. This process simple, quick, precise. method demonstrated peak symmetry, low processing times, good resolution, correlation values 0.999. For GAT, linearity ranged from 0.001 0.023 mgmL-1, while BEN, it 0.003 0.060 mgmL-1 HPLC system, UV range 0.005-0.03 all drugs. A unique feature this integration multiple assessment tools, such as AGREE, AGREEprep, ComplexGAPI, ESA, BAGI, NEMI pictograms, providing an exhaustive appraisal methods' environmental impact enhancing robustness findings. In addition, cost-effective alternatives were explored using solvent complementary spectrophotometric procedures mean centering ratio spectra (MCR). Each technique showed respectable accuracy precision (RSD ≤ 2%) high r2 > 0.9990. proposed methodologies provide inexpensive, conventional approaches, promoting less harmful future quality control moving chemistry closer more methods.
