Features Of Eastman Isobutyric Acid

  1. High-purity aliphatic carboxylic acid with consistent batch-to-batch quality.

  2. Low water content for enhanced stability in sensitive synthesis reactions.

  3. Controlled acidity (pKa ~4.86) enabling precise reactivity in esterification and amidation processes.

  4. Excellent solubility in common organic solvents including acetone, ethanol, and ethyl acetate.

  5. Manufactured under strict ISO-certified quality systems with full traceability.

Typical Applications Of Eastman Isobutyric Acid

  1. Synthesis of isobutyrate esters used as flavor and fragrance intermediates.

  2. Production of pharmaceutical active ingredients (APIs) and prodrug derivatives.

  3. Chemical intermediate in the manufacture of specialty polymers and plasticizers.

  4. Reagent in agrochemical synthesis, particularly for herbicide and fungicide precursors.

  5. Building block for catalyst ligands and metal-organic frameworks (MOFs).
