General Information
Lenvatinib Impurities and Lenvatinib
Daicel Pharma offers worldwide delivery options for custom synthesis of Lenvatinib impurity standards, including crucial impurity standards such as 2,4-dichloro-7-methoxyquinoline-6-carboxamide, 3,4-dichloro-7-methoxyquinoline-6-carboxamide, 4-(4-amino-3-hydroxyphenoxy)-7-methoxyquinoline-6-carboxamide, 4-Amino-2,3,5-Trichlorophenol, Lenvatinib chloro impurity, Lenvatinib Impurity-10 and more. These impurity standards play a vital role in evaluating the purity and safety of Lenvatinib, an active pharmaceutical ingredient.
Lenvatinib [CAS: 417716-92-8] is an orally available receptor tyrosine kinase inhibitor and antineoplastic agent. It treats refractory renal cell carcinoma and advanced, metastatic medullary thyroid cancer.
Lenvatinib: Use and Commercial Availability
Lenvatinib treats unresectable or advanced hepatocellular carcinoma (HCC), radioactive iodine-refractory differentiated thyroid cancer (DTC), and advanced renal cell carcinoma (RCC). Marketed under the brand name Lenvima, it is a multiple receptor tyrosine kinase inhibitor that effectively inhibits VEGF receptors, leading to potent antiangiogenic effects. Furthermore, Lenvatinib blocks FGFR, RET, PDGFRa, and KIT, causing the suppression of malignant cell proliferation.
Lenvatinib Structure and Mechanism of Action 
The chemical name of Lenvatinib is 4-[3-Chloro-4-[[(cyclopropylamino)carbonyl]amino]phenoxy]-7-methoxy-6-quinolinecarboxamide. Its chemical formula is C21H19ClN4O4, and its molecular weight is approximately 426.9 g/mol.
Lenvatinib blocks the kinase activities of vascular endothelial growth factor (VEGF) receptors and fibroblast growth factor (FGF) receptors, FGFR1, 2, 3, and 4.
Lenvatinib Impurities and Synthesis
During the production1 of Lenvatinib, impurities can form as byproducts or degradation products. They may arise from the starting materials, intermediates, or reaction conditions. It is crucial to identify, characterize, and control these impurities to ensure the safety and efficacy of the drug. Analytical techniques such as high-performance liquid chromatography (HPLC) and mass spectrometry (MS) help detect and quantify impurities. Strict quality control measures ensure impurity levels remain within acceptable limits, thereby maintaining the purity and quality of Lenvatinib.
Daicel Pharma strictly adheres to cGMP standards and operates an analytical facility for preparing Lenvatinib impurity standards. We provide a range of Lenvatinib impurity standards, such as 2,4-dichloro-7-methoxyquinoline-6-carboxamide, 3,4-dichloro-7-methoxyquinoline-6-carboxamide, 4-(4-amino-3-hydroxyphenoxy)-7-methoxyquinoline-6-carboxamide, 4-Amino-2,3,5-Trichlorophenol, Lenvatinib chloro impurity, Lenvatinib Impurity-10 and more. Our impurity standards have a detailed Certificate of Analysis (CoA) and a comprehensive characterization report. The CoA encompasses data obtained through techniques, 1H NMR, 13C NMR, IR, MASS, and HPLC purity analysis2. Additional data, such as 13C-DEPT, can be provided upon request. We can synthesize unknown Lenvatinib impurity standards or degradation products. Each delivery has a comprehensive characterization report.
