In the demanding fields of pharmaceutical synthesis, agrochemical development, and advanced organic chemistry, the purity and precise specifications of chemical intermediates are not just details – they are foundational requirements. 3-Bromo-2-cyanopyridine (CAS 55758-02-6), a critical building block known for its green crystal appearance, is no exception. Ensuring you source this compound with the right purity levels and detailed specifications is paramount for the success and reproducibility of your synthesis projects.

The primary specification for 3-Bromo-2-cyanopyridine is its assay, typically stated as a percentage of the main compound. For most research and industrial applications, a purity of ≥98.0% is considered standard and highly desirable. This high level of purity minimizes the presence of unwanted side products or unreacted starting materials, which could interfere with subsequent reactions, lead to lower yields, or generate difficult-to-remove impurities in your final product.

Beyond the assay, other critical specifications include the physical appearance (green crystal), melting point range, and the absence of specific critical impurities. Manufacturers provide Certificates of Analysis (CoA) that detail these parameters. For procurement managers and scientists, reviewing the CoA thoroughly before purchase is essential. It verifies that the material meets the required standards for your particular application, whether it's for laboratory research or large-scale industrial manufacturing.

When looking to buy 3-Bromo-2-cyanopyridine, especially from international suppliers and manufacturers in China, it is important to communicate your specific needs clearly. While a standard ≥98.0% purity is common, some highly sensitive applications might require even higher purities or specific impurity profiling. Reputable suppliers will be transparent about their specifications and quality control measures.

Sourcing high-quality 3-Bromo-2-cyanopyridine with well-defined specifications ensures the reliability and efficiency of your chemical synthesis. It prevents costly rework, delays, and potential failures in your research or production lines. Prioritizing suppliers who offer detailed specifications and consistent quality will ultimately lead to more successful outcomes in your synthetic endeavors.
