    GLP impurities are a subset of impurities that are specifically relevant to pharmaceutical products and are regulated under Good Laboratory Practice guidelines. Unlike organic or inorganic impurities, GLP impurities are characterized by their potential impact on the safety or efficacy of pharmaceuticals.

    Analytical techniques such as chromatography (HPLC, GC), spectroscopy (UV-Vis, IR), mass spectrometry (MS), and nuclear magnetic resonance (NMR) are commonly employed to detect and quantify.

    Manufacturers can employ various strategies, including stringent raw material selection, optimized synthetic routes, purification processes, and strict quality control measures to minimize GLP impurities during manufacturing.

    Exceeding permissible limits of GLP impurities in pharmaceutical products can lead to regulatory non-compliance, jeopardizing product approval and market availability. Additionally, high levels of impurities may compromise product safety and efficacy, potentially causing adverse effects in patients
