In the precise world of chemical synthesis, understanding the specifications of your raw materials is as crucial as the reaction itself. For 4-Bromoisophthalic Acid (CAS: 6939-93-1), a vital intermediate in pharmaceutical, material science, and organic chemistry applications, attention to detail regarding its properties ensures successful outcomes. NINGBO INNO PHARMCHEM, a leading manufacturer and supplier, emphasizes the importance of these specifications and how they benefit your R&D and production needs.

The most critical specification for 4-Bromoisophthalic Acid is its purity. Our product typically boasts a purity of 97% or greater, often verified by High-Performance Liquid Chromatography (HPLC). This high purity is essential for applications where even minor contaminants can interfere with reaction pathways, affect product yield, or compromise the performance of the final material or drug. For instance, in complex multi-step syntheses, starting with a high-purity intermediate minimizes the risk of side reactions and simplifies purification steps. When you are ready to buy, always check the Certificate of Analysis (CoA) for detailed purity information.

The physical appearance of 4-Bromoisophthalic Acid is consistently described as a white to off-white crystalline powder and chunks. This physical form is typical for many organic acids and reflects its solid state at room temperature, supported by its relatively high melting point, which is reported to be between 297-299°C. A consistent appearance indicates good batch-to-batch uniformity, a key factor for reproducible manufacturing processes. If you are a procurement manager, this consistency assures you of receiving a reliable product every time.

Other important properties include its molecular formula (C8H5BrO4) and molecular weight (approximately 245.03 g/mol). These fundamental data points are crucial for stoichiometric calculations in your reaction planning. Additionally, information such as density and boiling point, while often estimated for such compounds, provides further context for handling and processing. The Acidity factor (pKa) of 2.48±0.10 highlights its acidic nature, which is relevant for understanding its behavior in solution and during reactions involving acid-base chemistry.
