Description

trans-Aconitic Acid Anhydride is a reactive anhydride derivative of aconitic acid, a naturally occurring tricarboxylic acid. This high-purity intermediate is valued for its role in synthesizing specialized polymers, fine chemicals, and pharmaceutical building blocks. It is particularly sought after by research institutions and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors for introducing the aconitic acid moiety into target molecules.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of novel active pharmaceutical ingredients (APIs) and prodrugs.
• Polymer Chemistry: Used as a monomer or cross-linking agent in the production of specialty polyesters, polyamides, and coatings with tailored properties.
• Agrochemical Synthesis: Intermediate in the manufacture of advanced herbicides, fungicides, and plant growth regulators.
• Fine Chemical Production: Serves as a precursor for various esters, amides, and other derivatives used in flavors, fragrances, and performance chemicals.
• Bioconjugation & Linker Chemistry: Utilized in biochemical research for modifying proteins, peptides, and other biomolecules.
• Academic & Industrial Research: A valuable reagent for methodological development and exploring new synthetic pathways in organic chemistry.

Quality Control

Our trans-Aconitic Acid Anhydride is manufactured under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation (IR, NMR), to ensure it meets the high standards required for synthetic applications. Certificates of Analysis (COA) documenting all critical parameters are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and must be kept under anhydrous conditions to prevent hydrolysis. Keep away from strong bases and oxidizing agents.
