For procurement managers in the chemical and pharmaceutical industries, securing a consistent and high-quality supply of raw materials is a critical responsibility. When it comes to specialized compounds like 4,7-Dihydroxy-1,10-Phenanthroline (CAS 3922-40-5), understanding the procurement landscape, especially from global manufacturing hubs like China, is essential. This guide aims to assist you in making informed decisions when you need to buy this important organic intermediate.

4,7-Dihydroxy-1,10-Phenanthroline is primarily known for its application as a phenanthroline stain, instrumental in the spectrophotometric determination of dissolved oxygen. Its unique ability to form a stable, colored complex with iron(II) in the presence of oxygen makes it a go-to reagent for accurate oxygen level monitoring. For R&D departments and quality control labs, this accuracy is non-negotiable, underscoring the need for high-purity grades, typically above 98% by HPLC.

When initiating a purchase, consider the key specifications: Molecular Formula (C12H8N2O2), Molecular Weight (212.21 g/mol), and its physical form (powder). It's also important to note its high melting point (often above 300°C with decomposition) and its insolubility in water, which may affect solution preparation. Engaging with manufacturers who provide detailed technical data and safety information is crucial.

China has emerged as a leading global supplier of chemical intermediates. When seeking to buy 4,7-Dihydroxy-1,10-Phenanthroline, identifying reputable Chinese manufacturers is a strategic move. Look for companies that demonstrate a commitment to quality control, have established production facilities, and offer transparent pricing for bulk orders. Requesting samples and Certificates of Analysis (COA) for each batch is a standard practice to verify product integrity and compliance with your specifications.

Understanding the pricing structures for different quantities is also part of a smart procurement strategy. Whether you require small quantities for laboratory research or larger volumes for industrial processes, obtaining quotes from multiple suppliers will help you secure the best possible price for 4,7-Dihydroxy-1,10-Phenanthroline. Factors like packaging options (e.g., 1g, 10g, 100g, bulk) and delivery timelines should also be considered.

Beyond its analytical applications, 4,7-Dihydroxy-1,10-Phenanthroline can serve as a versatile intermediate in organic synthesis. Therefore, maintaining a robust relationship with a reliable supplier can support ongoing research and development efforts. For seamless procurement, clear communication regarding your specific needs and expected quality standards is key when contacting manufacturers and suppliers for this chemical compound.
