For professionals in the chemical and pharmaceutical industries, understanding the precise specifications and proper handling of chemical intermediates is fundamental to successful research and manufacturing. 2,4-Dibromothiazole-5-carbaldehyde, identified by CAS number 139669-95-7, is a chemical compound that demands careful attention to its properties and storage requirements.
The molecular formula for this compound is C4HBr2NOS, with a molecular weight of 270.93. A key specification that buyers look for is its purity, which is typically stated as 99% minimum. This high purity ensures that the compound is suitable for sensitive applications in organic synthesis and pharmaceutical development, minimizing the risk of impurities interfering with reactions or final product quality.
Physically, 2,4-Dibromothiazole-5-carbaldehyde is described as a light yellow to brown solid. Its melting point is recorded at 99.8°C, providing a clear indicator of its solid state under standard laboratory conditions. The density is approximately 2.332 g/cm³. While a boiling point of 317°C at 760 mmHg is noted, its handling and use often occur at temperatures below its melting point.
Proper storage is critical for maintaining the integrity and shelf-life of this intermediate. Suppliers generally recommend storing 2,4-Dibromothiazole-5-carbaldehyde in a well-closed container, protected from light and moisture, in a cool and dry place. Specifically, maintaining a temperature between 2-8°C is often advised. Adhering to these storage conditions is essential for any research or development laboratory aiming to preserve the quality of the chemical.
When sourcing this material, it is advisable to obtain the Material Safety Data Sheet (MSDS) and Certificate of Analysis (CoA) from the manufacturer. These documents provide comprehensive information on safety precautions, handling procedures, first-aid measures, and the exact specifications of the batch received. Suppliers often make these available upon request or with the product shipment.
In summary, familiarizing oneself with the specific properties and recommended handling procedures for 2,4-Dibromothiazole-5-carbaldehyde is a crucial step for anyone involved in its procurement or use. By adhering to these guidelines, researchers and chemists can ensure the quality and effectiveness of this important pharmaceutical intermediate in their projects.
