For professionals in the chemical industry—be it pharmaceutical research, agrochemical development, or advanced material synthesis—a deep understanding of chemical specifications is non-negotiable. Succinic Anhydride (CAS 108-30-5) is a widely used intermediate, and its quality directly impacts the outcome of various manufacturing processes. This article serves as a buyer's guide to understanding the critical specifications of Succinic Anhydride and how to leverage this knowledge when selecting a supplier.

The most crucial specification for Succinic Anhydride is its purity, often expressed as an assay percentage. For pharmaceutical and demanding industrial applications, a high assay, typically 99% MIN, is required. This high purity ensures minimal presence of impurities that could interfere with reactions, affect product performance, or lead to regulatory issues. Manufacturers like NINGBO INNO PHARMCHEM CO.,LTD. emphasize this high assay as a cornerstone of their product quality. When you buy Succinic Anhydride, always verify the purity declared on the Certificate of Analysis (COA).

Beyond purity, the physical appearance of Succinic Anhydride is a key identifier. It is typically described as white flaky crystals. Any deviation from this standard appearance could indicate contamination or improper storage and handling. This visual cue is often the first indicator of the material's quality, complementing the detailed assay results.

Another important aspect is the CAS number: 108-30-5. This unique identifier ensures that you are procuring the correct chemical compound, preventing costly errors in synthesis or formulation. When inquiring about prices or placing an order for Succinic Anhydride, always reference this CAS number to avoid confusion.

For procurement managers, understanding the typical packaging, such as 25kg drums, is also relevant for logistics and handling within a manufacturing facility. Furthermore, reliable suppliers will provide comprehensive Safety Data Sheets (SDS) that detail safe handling procedures, hazard information, and environmental precautions. This documentation is vital for maintaining a safe working environment and adhering to compliance standards.

When sourcing Succinic Anhydride, especially from international markets like China, choosing a manufacturer that is transparent about its specifications and quality control processes is paramount. A supplier that can consistently deliver Succinic Anhydride meeting these critical specifications—high assay, correct appearance, and proper documentation—will be an invaluable partner in your business operations. Always prioritize quality and reliability when you purchase chemical intermediates.
