Description

2-Propylpentanoic Anhydride is a high-purity organic acid anhydride, a key reactive intermediate in advanced chemical synthesis. Its primary value lies in its role as a versatile acylating agent, enabling the efficient introduction of the 2-propylpentanoyl moiety into target molecules. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries, particularly for the development of active pharmaceutical ingredients (APIs) and fine chemicals.

Application

• Pharmaceutical Intermediate: Critical for the synthesis of valproic acid derivatives and other central nervous system (CNS) active compounds.
• Agrochemical Synthesis: Used in the production of advanced pesticides and herbicides requiring specific acyl group functionalities.
• Polymer Chemistry: Acts as a monomer or modifier in the synthesis of specialty polyesters and polyamides with tailored properties.
• Fine Chemical Production: Serves as a building block for fragrances, flavors, and other high-value organic compounds.
• Academic & R&D: A valuable reagent for methodological development in organic synthesis and medicinal chemistry research.
• Chemical Derivatization: Employed in analytical chemistry for the derivatization of compounds for GC or HPLC analysis.

Quality Control

Our 2-Propylpentanoic Anhydride is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including assay, impurity profiling, and identity confirmation, to ensure it meets the high standards required for pharmaceutical and fine chemical applications. Certificates of Analysis (COA) documenting purity, physical characteristics, and safety data are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis. Keep away from strong acids, bases, and oxidizing agents.
