For any B2B purchaser of chemical intermediates, understanding product specifications is not just a formality; it's a critical aspect of ensuring successful downstream applications and cost-effectiveness. 1,3-Dibromo-5-fluorobenzene (CAS 1435-51-4), a vital compound in organic synthesis, is no exception. The key specifications that buyers must scrutinize are its purity and assay, which dictate its reliability and performance in various chemical processes.

The assay of 1,3-Dibromo-5-fluorobenzene typically refers to the minimum percentage of the desired compound present in the sample, often determined by analytical techniques such as Gas Chromatography (GC). Sources commonly indicate an assay of ≥98.0% or ≥99.0%. A higher assay means a greater concentration of the active compound and fewer impurities, which is particularly important for sensitive reactions like those in pharmaceutical synthesis. When you buy 1,3-Dibromo-5-fluorobenzene from a reputable manufacturer, you can expect a detailed Certificate of Analysis (CoA) that clearly states the tested assay and the methodology used.

Purity is closely related to assay but also encompasses the nature and quantity of specific impurities. For intermediates like 1,3-Dibromo-5-fluorobenzene, potential impurities could include starting materials, by-products from synthesis, or residual solvents. These impurities can interfere with reaction mechanisms, lead to lower yields, or even introduce undesirable characteristics into the final product. Therefore, selecting a supplier like NINGBO INNO PHARMCHEM CO.,LTD., known for its stringent quality control and commitment to high purity, is paramount.

When engaging with suppliers, always inquire about their typical assay and purity profiles, and request sample CoAs. Understanding these specifications will empower you to make informed purchasing decisions and ensure that the 1,3-Dibromo-5-fluorobenzene you buy meets the exacting standards of your research or manufacturing processes. For those seeking high-purity 1,3-Dibromo-5-fluorobenzene with a guaranteed assay, NINGBO INNO PHARMCHEM offers reliable sourcing solutions from China.
