For pharmaceutical manufacturers engaged in the production of complex APIs like Cabozantinib, sourcing high-purity intermediates is a critical step. 4-(6,7-Dimethoxyquinolin-4-yl)oxyaniline, a key building block for this important tyrosine kinase inhibitor, requires meticulous quality control throughout its synthesis and supply chain. This article aims to guide manufacturers in understanding the key specifications and considerations when looking to purchase this essential compound.

The chemical properties of 4-(6,7-Dimethoxyquinolin-4-yl)oxyaniline, including its appearance as a white to light yellow powder and its molecular formula C17H16N2O3, are well-documented. However, the most critical specification for pharmaceutical applications is its purity, typically measured by HPLC and often required to be ≥98.0%. This high level of purity ensures that the intermediate will not introduce unwanted impurities into the final Cabozantinib product, a crucial factor for regulatory approval and patient safety. Understanding the synthesis pathways for this compound is also beneficial. Common methods involve the reaction of 4-chloro-6,7-dimethoxyquinoline with 4-aminophenol, a process that can be optimized for yield and purity. Manufacturers may research different synthesis routes to ensure they are procuring the most cost-effective and highest-quality material. The price of this intermediate can vary based on supplier, quantity, and purity, making it important to compare offers from various producers.

When considering where to buy 4-(6,7-Dimethoxyquinolin-4-yl)oxyaniline, China stands out as a prominent hub for pharmaceutical intermediate manufacturing. Numerous suppliers in China offer this compound, leveraging advanced production facilities and skilled labor to provide competitive pricing. Partnering with a reputable 4-(6,7-dimethoxyquinolin-4-yl)oxyaniline supplier in China means gaining access to reliable quality, consistent supply, and potentially better bulk purchase options. It's advisable to vet potential suppliers thoroughly, checking for certifications, quality control procedures, and customer testimonials. Beyond the product itself, customer service, including tailored packaging and efficient logistics, plays a significant role in a successful partnership. For companies focused on streamlining their supply chain and ensuring the consistent availability of critical raw materials, identifying and working with trusted manufacturers like NINGBO INNO PHARMCHEM CO.,LTD. can provide a significant competitive advantage.
