Biological Activity
Gefitinib impurity 1 is a compound derived from Gefitinib, a potent and selective EGFR tyrosine kinase inhibitor (IC 50 = 33 nM). This orally active compound selectively inhibits tumor cell growth stimulated by EGF (IC 50 = 54 nM) and inhibits EGFR autophosphorylation induced by EGF in tumor cells. Additionally, Gefitinib induces autophagy and exhibits antitumor activity.
Safety & Regulatory
For Research Use Only (RUO). Not for therapeutic, diagnostic, or clinical use. Wear appropriate PPE and consult the Safety Data Sheet (SDS) prior to handling.
Try the following steps: (1) warm the DMSO solvent to 37–50 °C before adding the compound; (2) vortex vigorously for 30 seconds then bath-sonicate for 1–2 minutes; (3) if still undissolved, prepare a more dilute stock. Note that maximum solubility values are reference conditions — actual solubility can vary with temperature, solvent lot, and compound batch. Contact BioHippo support if dissolution problems persist.
For currently available products, batch-specific purity data (HPLC chromatogram, NMR spectrum, and Certificate of Analysis) is accessible via the DataSheet link on the product page. For future or custom synthesis products, purity determination is conducted upon availability and published on the product page. Contact BioHippo for batch-specific CoA requests or custom synthesis enquiries.
