Our dedicated quality unit employs state-of-the-art analytical equipment including high-performance liquid chromatography (HPLC), Fourier-transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), and powder X-ray diffraction (PXRD) to ensure total batch-to-batch consistency and rigorous quality control.
We solve critical supply bottlenecks in oncology API procurement. By integrating intermediate synthesis with final API crystallization, we help global bio-generic developers lower overall R&D costs and reduce time-to-market for bioequivalent oral cancer therapies targeting Renal Cell Carcinoma (RCC) and Soft Tissue Sarcoma (STS).
As the patent landscape for target oncology drugs evolves, worldwide demand for scalable, cost-effective Pazopanib raw materials has surged across North America, Latin America, Europe, Asia-Pacific, and Africa. Our contract manufacturing services provide scalable batch outputs ranging from kilo-lab quantities up to multi-ton commercial orders.
Gentolex maintains localized support infrastructure, with dedicated market representatives established in regional hubs like Mexico and South Africa. We provide complete Drug Master File (DMF) support, Certificate of Analysis (CoA), Stability Data (ICH zones), and regulatory liaison services for fast local registration.
Gentolex’s goal is to create opportunities connecting the world with better services and guaranteed products. Up to date, Gentolex Group has been serving customers from more than 10 countries, specially, representatives are established in Mexico and South Africa.
