For professionals in the pharmaceutical and chemical research sectors, sourcing high-quality intermediates is paramount. 1-Methyl-3-nitrophthalate (CAS 21606-04-2) is one such compound, frequently utilized as a key building block in sophisticated organic synthesis and as an intermediate in the preparation of specific pharmaceutical impurities, such as those related to Apremilast. As a discerning buyer, understanding where to procure this chemical reliably is crucial for project success.

When you need to buy 1-Methyl-3-nitrophthalate, prioritizing suppliers who guarantee high purity (typically ≥99%) and consistent quality is essential. Many research initiatives and manufacturing processes depend on the precise chemical composition and physical characteristics of intermediates like this one. The compound is usually supplied as a white to light yellow crystalline powder, a form that facilitates accurate weighing and handling in laboratory settings.

For those seeking a dependable 1-Methyl-3-nitrophthalate manufacturer in China, looking for established chemical suppliers with robust quality control systems is advisable. Companies that specialize in pharmaceutical intermediates and fine chemicals often have the infrastructure and expertise to produce and supply this compound consistently. The price of 1-Methyl-3-nitrophthalate can vary based on quantity, purity, and supplier, so obtaining multiple quotes is a standard practice for procurement managers.

Furthermore, considering the supplier's experience in handling and exporting chemical products is beneficial. A reliable partner will provide comprehensive documentation, including Certificates of Analysis (CoA), to verify the product’s specifications. Engaging with manufacturers who offer technical support can also be invaluable, especially when integrating new intermediates into established synthesis routes.

In summary, securing a stable supply of high-purity 1-Methyl-3-nitrophthalate from a reputable Chinese manufacturer is a key step for many research and development projects. By focusing on quality, reliability, and competitive pricing, you can ensure the seamless progression of your chemical synthesis objectives.
