Key Specifications for Purchasing 3-Bromophthalic Anhydride (CAS 82-73-5)
When procuring chemical intermediates like 3-Bromophthalic Anhydride (CAS 82-73-5), understanding and verifying key specifications is non-negotiable. For chemists, formulators, and procurement specialists, these details ensure the compound's suitability for specific applications, guaranteeing optimal performance and reproducible results. This guide highlights the essential specifications buyers should look for when they intend to buy 3-Bromophthalic Anhydride.
The most critical specification is undoubtedly purity. For 3-Bromophthalic Anhydride, a high purity level, typically stated as ≥98.0% or even 99.0% (often verified by techniques like HPLC or GC), is vital. Impurities can interfere with synthesis reactions, affect reaction yields, and potentially compromise the quality of the final product. Researchers often require precise chemical entities for sensitive organic synthesis pathways, and consistently high purity is a hallmark of a quality manufacturer.
Another crucial parameter is the moisture content. As an anhydride, 3-Bromophthalic Anhydride is susceptible to hydrolysis, a reaction where it reacts with water to form the corresponding acid (3-bromophthalic acid). High moisture content will reduce the effective concentration of the anhydride and can initiate unwanted side reactions. Therefore, a specification of ≤0.1% moisture content is highly desirable and indicative of proper manufacturing and packaging practices by the supplier.
The physical appearance is also important, though often subjective. 3-Bromophthalic Anhydride is typically described as an off-white to white powder or crystalline solid. Any significant deviation from this description, such as an intense color or the presence of foreign particles, warrants further investigation into the product's quality and potential contaminants.
Beyond these core attributes, buyers may also consider other specifications like particle size distribution if relevant to their specific application, or specific impurity profiles if known to be problematic for their synthesis. When obtaining quotes from various suppliers, always compare the detailed specifications provided in their product data sheets or CoAs. Understanding these parameters empowers you to make informed purchasing decisions, ensuring you obtain 3-Bromophthalic Anhydride that meets your exacting requirements and supports the success of your chemical endeavors.
