A novel sensitive and validated spectrofluorimetric framework for betrixaban determination in different matrices using erythrosine B–based fluorescence quenching
A novel, sensitive, and eco-friendly spectrofluorimetric approach was developed for quantifying betrixaban. This technique is based on quenching the intrinsic fluorescence of erythrosine B in an acidic Toerell–Stenhagen buffer (pH 4.0). Stern-Volmer analysis confirmed the formation of a non-fluorescent ion-pair complex...
