For procurement managers and R&D scientists in the pharmaceutical sector, securing a reliable supply of high-quality intermediates is paramount. 7-Hydroxy-3,4-dihydro-2(1H)-quinolinone (CAS: 22246-18-0) is one such critical compound, serving as a key building block in the synthesis of Aripiprazole, a widely prescribed antipsychotic medication. Understanding where and how to buy this intermediate can significantly impact production efficiency and product quality.

When looking to purchase 7-Hydroxy-3,4-dihydro-2(1H)-quinolinone, the primary considerations revolve around purity, supplier reliability, and competitive pricing. Manufacturers and suppliers often list specifications such as appearance (typically off-white to pale yellow powder), assay (generally ≥98.0%), melting point, and loss on drying. These parameters are crucial for ensuring the intermediate meets the stringent requirements for pharmaceutical applications. For example, an assay of ≥98.0% is commonly sought after to guarantee minimal impurities that could affect the final Aripiprazole product.

Identifying reputable manufacturers and suppliers in China is often the most efficient route for obtaining this intermediate. Companies specializing in pharmaceutical intermediates and fine chemicals are well-positioned to offer this product. When inquiring about price, it's advisable to request quotes for various quantities, as bulk purchases often come with significant discounts. Factors like delivery time, packaging options (commonly 25 kg drums), and the availability of supporting documentation, such as Certificates of Analysis (CoA) and Material Safety Data Sheets (MSDS), are also important aspects of the sourcing process.

The search for terms like 'buy 7-Hydroxy-3,4-dihydro-2(1H)-quinolinone,' '22246-18-0 supplier China,' or 'Aripiprazole intermediate manufacturer' will yield numerous results. However, due diligence is key. Look for suppliers that highlight their quality control processes and adherence to industry standards. For instance, understanding the synthesis route and impurity profile can provide further confidence in the product's suitability for your specific needs. Companies committed to transparency and customer support are often the best partners.

In addition to its role in Aripiprazole synthesis, 7-Hydroxy-3,4-dihydro-2(1H)-quinolinone is also noted for its potential as an antitumor agent and a tyrosinase inhibitor. This dual utility can make it a valuable compound for research scientists exploring new therapeutic avenues. Therefore, when sourcing, consider not only the immediate need for Aripiprazole production but also the broader research potential of this versatile molecule.

Ultimately, selecting the right manufacturer or supplier for 7-Hydroxy-3,4-dihydro-2(1H)-quinolinone involves a balance of quality, cost, and reliability. By focusing on key specifications, seeking competitive pricing through bulk inquiries, and partnering with experienced chemical suppliers, procurement teams can ensure a stable and high-quality supply of this indispensable pharmaceutical intermediate.
