For chemists engaged in advanced organic synthesis and the development of pharmaceutical intermediates, a thorough understanding of the specifications of raw materials is non-negotiable. 2,5-Dibromo-1,3-Dichlorobenzene (CAS No.: 19393-97-6) is one such compound where detailed specifications directly influence its suitability and performance in various reactions.

The most critical specification for 2,5-Dibromo-1,3-Dichlorobenzene is its purity, typically stated as ≥99%. This high degree of purity is essential for ensuring predictable reaction outcomes and minimizing the presence of unwanted side products. In pharmaceutical synthesis, even minor impurities can lead to the formation of difficult-to-separate byproducts or affect the efficacy and safety of the final Active Pharmaceutical Ingredient (API). Therefore, scientists and formulators must ensure they source material that consistently meets this purity threshold.

The appearance of the compound is also a key indicator of its quality and handling. 2,5-Dibromo-1,3-Dichlorobenzene is described as a colorless to light yellow transparent liquid. Deviations from this description, such as a pronounced color change or turbidity, might suggest degradation or the presence of impurities, prompting further investigation or rejection of the batch.

Beyond purity and appearance, understanding the molecular properties is fundamental. The molecular formula C6H2Br2Cl2 and a molecular weight of approximately 304.79 g/mol are standard identifiers. These figures are crucial for stoichiometric calculations in synthesis, ensuring the correct molar ratios are used for reactions. The precise arrangement of bromine and chlorine atoms on the benzene ring (2,5-dibromo and 1,3-dichloro substitution) dictates its reactivity and suitability as a building block.

For procurement specialists and R&D scientists looking to buy 2,5-Dibromo-1,3-Dichlorobenzene, checking these specifications is a primary step. Reliable manufacturers will readily provide this information, often in the form of a Certificate of Analysis (CoA) accompanying each order. This document serves as proof of quality and conformity to the stated specifications.

When searching for a supplier, it’s beneficial to partner with manufacturers who can guarantee these specifications consistently. Whether you are performing small-scale laboratory experiments or large-scale industrial synthesis, the quality of your starting materials directly impacts the success of your project. Therefore, prioritizing suppliers who clearly communicate and adhere to high standards for 2,5-Dibromo-1,3-Dichlorobenzene ensures greater efficiency and reliability in your chemical processes.
