For successful chemical research and development, a thorough understanding of the specifications of the starting materials is crucial. 2-Bromo-5-chloropyridine, identified by its CAS number 40473-01-6, is a chemical intermediate whose properties are well-defined to ensure its effective use.

The primary specification for 2-Bromo-5-chloropyridine is its appearance, which is consistently described as a white to off-white solid. This physical characteristic is a basic quality check, indicating the material's general state. Beyond appearance, the purity or assay of the compound is of utmost importance. For 2-Bromo-5-chloropyridine, the typical assay is u226597.0%. This high purity level is critical for organic synthesis, as impurities can interfere with reaction pathways, reduce yields, or lead to the formation of undesired by-products.

The CAS number, 40473-01-6, serves as a unique identifier for this compound, ensuring that researchers are referencing the correct chemical entity. In chemical research, precise identification is the first step towards reliable experimental design. Beyond purity, other physicochemical properties such as melting point (typically 65-69 u00b0C), boiling point, and density also inform chemists about the compound's behavior under various conditions. These details are often found in technical data sheets provided by reputable manufacturers or suppliers.

Proper storage conditions are also a critical specification for maintaining the integrity of 2-Bromo-5-chloropyridine. The material is generally recommended to be stored in a cool, ventilated place, often in tightly sealed containers to protect it from moisture and air. Adhering to these storage guidelines helps preserve its chemical stability and assay over time, ensuring its suitability for research applications.

When sourcing 2-Bromo-5-chloropyridine for your chemical research, paying close attention to these specifications is essential. Working with manufacturers or suppliers that provide comprehensive Certificates of Analysis (CoA) confirms the material meets the stated purity and quality standards. This diligence ensures that your synthesis projects are built upon a foundation of reliable, high-quality chemical intermediates, paving the way for accurate and impactful research outcomes.
