For professionals in the chemical and pharmaceutical industries, understanding the precise specifications of raw materials is critical for successful applications. 6,7-Dimethoxy-3,4-dihydroquinazolin-4-one (CAS: 13794-72-4) is a compound whose quality directly impacts downstream processes, particularly in pharmaceutical synthesis.

When procuring 6,7-Dimethoxy-3,4-dihydroquinazolin-4-one, the primary specification to scrutinize is its purity, typically measured by High-Performance Liquid Chromatography (HPLC). A minimum purity of >98% HPLC is generally considered the standard for this compound, especially when it is intended for use as a pharmaceutical intermediate or a research chemical. This high level of purity minimizes unwanted side reactions and ensures the integrity of synthesized products, such as Gefitinib.

The appearance of the compound is also an important indicator of its quality and handling. 6,7-Dimethoxy-3,4-dihydroquinazolin-4-one is typically described as a white to near-white solid powder. Variations in color or texture might suggest impurities or degradation, prompting closer examination of the supplier's quality control measures.

The Chemical Abstracts Service (CAS) number, 13794-72-4, serves as a unique identifier for this substance, essential for accurate ordering and documentation. When searching for this compound, using the CAS number ensures that you are referencing the correct chemical entity.

For procurement managers and R&D scientists, identifying a reliable supplier is as crucial as verifying the product specifications. A trusted manufacturer or distributor will readily provide a Certificate of Analysis (COA) detailing the purity, analytical methods used, and other relevant properties. They will also offer comprehensive Safety Data Sheets (SDS) and be transparent about their manufacturing processes.

Whether you are looking to buy 6,7-Dimethoxy-3,4-dihydroquinazolin-4-one for large-scale manufacturing or for specialized research purposes, prioritizing these specifications and supplier credibility will lead to more efficient and successful outcomes. Engaging with a manufacturer that understands these requirements is key to establishing a strong supply chain for your chemical needs.
