Overview
Osimertinib Intermediate is a critical precursor in the synthesis of Osimertinib, a targeted therapy drug for EGFR-mutated non-small cell lung cancer (NSCLC). As a specialized pharmaceutical intermediate, it undergoes further chemical transformations to form the active pharmaceutical ingredient (API). Its production requires stringent quality control to ensure compliance with regulatory standards such as ICH guidelines. Pharmaceutical manufacturers rely on high-purity intermediates to maintain the efficacy and safety of the final drug product. The intermediate’s synthesis involves multi-step organic reactions, often requiring advanced expertise in medicinal chemistry and process optimization.
Physical and Chemical Properties
The intermediate typically appears as a white to off-white crystalline powder, with solubility in polar organic solvents like dimethyl sulfoxide (DMSO) and methanol. Its stability is influenced by storage conditions, with recommended protection from light, moisture, and extreme temperatures to prevent degradation. While specific molecular weight and formula are proprietary, the compound’s structural features align with its role in forming Osimertinib’s core scaffold. Analytical techniques such as HPLC and NMR are used to confirm purity and identity, with commercial batches often exceeding 98% purity.
Main Applications
This intermediate is exclusively used in the pharmaceutical industry for Osimertinib API production. Osimertinib, marketed as Tagrisso®, is a third-generation EGFR inhibitor effective against T790M resistance mutations in NSCLC patients. The intermediate’s quality directly impacts the API’s yield, potency, and regulatory compliance. Global demand for the intermediate has grown alongside Osimertinib’s adoption as a first-line treatment. Contract manufacturing organizations (CMOs) and API producers are key stakeholders, often requiring bulk quantities under long-term supply agreements.
Safety and Storage
Handling requires standard laboratory precautions, including gloves, goggles, and fume hoods to minimize exposure. While toxicity data is limited, it should be treated as a potentially hazardous chemical due to its pharmacological activity. Spills should be contained with inert absorbents and disposed of as pharmaceutical waste. Storage recommendations include airtight containers under inert gas (e.g., nitrogen) at controlled room temperature (15–25°C). Prolonged exposure to humidity or heat may compromise stability, necessitating regular quality checks for long-term storage.
B2B Procurement Guide
Buyers should prioritize suppliers with documented GMP compliance and audited manufacturing facilities. Key procurement criteria include batch-to-batch consistency, impurity profiles (e.g., genotoxic impurities), and regulatory support (e.g., DMF filings). Pricing varies significantly based on order volume, purity grade (e.g., 98% vs. 99.5%), and supply chain logistics. Due to the intermediate’s specialized nature, sample testing and supplier qualification are essential. Negotiating multi-year contracts with backup suppliers can mitigate supply chain risks, especially given geopolitical or regulatory uncertainties in API production hubs like China and India.
