Cefpodoxime Proxetil is used as a chemical reference standard (CRS) to identify and quantify the drug in formulations or biological samples. In chromatographic methods like HPLC or LC-MS, the CRS allows peak identification, ensuring that the detected peak corresponds precisely to cefpodoxime proxetil. This is critical for quality control, assay validation, and purity testing, confirming that the drug in a sample matches the standard in terms of retention time, peak shape, and response.
