For professionals in the chemical and pharmaceutical industries, a deep understanding of the properties of key compounds is essential. Sulfadimethoxypyrimidine, identified by its CAS number 155-91-9, is a prominent sulfonamide with significant antibacterial applications. This profile aims to provide a detailed look at its chemical characteristics, aiding procurement managers and researchers in making informed decisions when they intend to buy Sulfadimethoxypyrimidine.

Chemically, Sulfadimethoxypyrimidine has the molecular formula C12H14N4O4S and a molecular weight of approximately 310.33 g/mol. Its physical appearance is a white or creamy-white crystalline powder, a key characteristic for quality assessment. The compound exhibits specific solubility properties: it is insoluble in water but slightly soluble in ethanol. It is more soluble in acetone and readily dissolves in dilute mineral acids and strong alkali solutions. Understanding these solubility characteristics is crucial for formulators working with Sulfadimethoxypyrimidine.

A significant physical property of Sulfadimethoxypyrimidine is its melting point, which typically falls within the range of 172.5°C to 202°C, depending on the specific grade and purity. The compound is also noted to be sensitive to light, which can lead to gradual deterioration and color change. Therefore, proper storage in light-resistant containers is vital to maintain its quality and shelf life, a detail that all buyers should confirm with their Sulfadimethoxypyrimidine manufacturer.

In terms of chemical specifications relevant to its use as a pharmaceutical ingredient, key parameters include limits for heavy metals (NMT 10ppm), loss on drying (NMT 0.5%), and residue on ignition (NMT 0.1%). The assay, as mentioned, is typically 98.5%-101.0%, ensuring a high concentration of the active compound. These specifications are critical for companies seeking to purchase Sulfadimethoxypyrimidine that meets stringent industry standards.

As a long-acting sulfonamide, Sulfadimethoxypyrimidine's primary application is in combating bacterial infections. Its broad-spectrum activity makes it effective against a range of diseases. For those looking to procure this compound, working with a reputable Sulfadimethoxypyrimidine supplier in China ensures access to detailed technical data and consistent product quality. When seeking a chemical supplier, always verify their product specifications align with your intended use, especially for pharmaceutical-grade Sulfadimethoxypyrimidine.
