For professionals in organic chemistry, understanding the nuances of key intermediates is vital for successful synthesis. 2,5-Dibromo-4-methylpyridine (CAS 3430-26-0) is one such compound, offering a versatile platform for creating complex organic molecules. This article aims to provide a comprehensive overview of its chemical properties, synthesis methods, and essential handling considerations, valuable for researchers and procurement managers looking to buy this compound.

Chemical Profile and Physical Characteristics

2,5-Dibromo-4-methylpyridine, also referred to as 2,5-Dibromo-4-picoline, boasts a molecular formula of C6H5Br2N and a molecular weight of approximately 250.92 g/mol. Its appearance is typically a white to light yellow or orange solid, with melting points reported in various ranges, often around 37-41°C or higher for purified forms. This solid state at room temperature simplifies handling for many applications. The compound is generally soluble in common organic solvents such as dichloromethane, THF, and DMSO, but shows low solubility in water, a property that aids in its isolation and purification during synthesis. Understanding these physical properties is crucial for chemists when planning reactions and for procurement managers ensuring the correct material is ordered.

Synthesis Routes and Considerations

The synthesis of 2,5-Dibromo-4-methylpyridine typically involves bromination of a suitable pyridine precursor. One common approach involves the direct bromination of 4-methylpyridine derivatives under specific reaction conditions, often employing brominating agents like elemental bromine or N-bromosuccinimide (NBS) in the presence of catalysts. Careful control of temperature and reagent stoichiometry is necessary to ensure regioselectivity and minimize the formation of unwanted by-products. Protection/deprotection strategies or directed metallation can also be employed to achieve precise substitution patterns. For businesses aiming to purchase this intermediate, the synthesis route employed by the manufacturer can influence its final purity and cost. A well-established supplier will provide detailed information on their synthesis processes.

Safe Handling and Storage Practices

Proper handling and storage are critical to maintaining the integrity and safety of 2,5-Dibromo-4-methylpyridine. As with many halogenated organic compounds, it should be stored in a cool, dry, and well-ventilated area, away from direct sunlight, heat, and incompatible materials such as strong oxidizing agents. Containers should be kept tightly closed to prevent moisture absorption and potential degradation. When handling, appropriate personal protective equipment (PPE), including gloves, eye protection, and lab coats, should be used to avoid skin and eye contact. Adherence to these safety protocols is essential for both laboratory personnel and for maintaining the quality of the product when you buy it from a manufacturer.

Procurement from Reliable Suppliers in China

For efficient procurement, engaging with a reputable supplier in China offers significant advantages. These suppliers often provide high-quality 2,5-Dibromo-4-methylpyridine at competitive prices, backed by comprehensive technical data and support. When you decide to buy 2,5-Dibromo-4-methylpyridine, selecting a supplier with a proven track record for quality control and timely delivery will ensure your research and production needs are met effectively.
