The market for Gefitinib-related compounds, encompassing intermediates, impurities, and reference standards, is a specialized segment within the pharmaceutical chemical industry. For procurement professionals and researchers, navigating this market effectively requires a clear understanding of product specifications, supplier reliability, and current market dynamics. This guide aims to provide buyers with key considerations when sourcing compounds like 7-Methoxy-6-(3-morpholin-4-ylpropoxy)quinazolin-4(3H)-one (CAS: 199327-61-2).

Understanding Gefitinib Intermediates and Impurities

Gefitinib, a vital targeted therapy, is produced through complex synthesis routes that involve several precursor molecules. Intermediates such as 7-Methoxy-6-(3-morpholin-4-ylpropoxy)quinazolin-4(3H)-one are critical for building the final active pharmaceutical ingredient (API). Additionally, understanding and sourcing impurities, such as Gefitinib Impurity A (which is often the same compound or a closely related structure), is crucial for quality control and regulatory compliance. Buyers typically search for specific CAS numbers or chemical names, along with terms like 'buy Gefitinib intermediate' or 'purchase Gefitinib impurity'.

Supplier Identification and Evaluation

When looking to buy 7-Methoxy-6-(3-morpholin-4-ylpropoxy)quinazolin-4(3H)-one, buyers often turn to specialized chemical directories and B2B platforms. Identifying a reputable manufacturer or supplier is the first step. Key evaluation criteria include: 1) confirmed purity (e.g., >99.0% HPLC), 2) consistent appearance (White to Off-White Powder), 3) reliability of supply (stock availability, production capacity), and 4) competitive pricing. Suppliers based in China are often a primary source due to their manufacturing capabilities and market presence. It's advisable to obtain quotes from multiple vendors and thoroughly review their quality documentation.

Quality Verification and Best Practices

Beyond initial supplier identification, buyers should prioritize quality verification. Requesting samples for in-house testing or detailed CoAs that include batch-specific analytical data is a standard practice. For critical pharmaceutical intermediates, understanding the supplier’s quality management system and regulatory compliance is also important. Building a relationship with a trusted supplier who provides excellent customer service, fast delivery, and technical support can streamline the procurement process and ensure the successful integration of these compounds into your projects. When inquiring, using phrases like 'quote for CAS 199327-61-2' or 'price of Gefitinib intermediate' will help you connect with relevant vendors.
