Description

Isobutyric Acid CAS NO 79-31-2 is a short-chain carboxylic acid characterized by its pungent odor and versatile chemical reactivity. This compound is a valuable intermediate and additive, prized for its role in synthesizing esters, pharmaceuticals, and flavoring agents. It serves as a critical raw material for manufacturers in the agrochemical, fragrance, food, and pharmaceutical industries seeking reliable, high-purity chemical building blocks.

Application

• Flavor and Fragrance Industry: Used as a precursor in the synthesis of esters like ethyl isobutyrate, which are key components in fruit flavors (e.g., raspberry, strawberry) and perfumery.
• Pharmaceutical Intermediates: Acts as a crucial building block in the synthesis of various active pharmaceutical ingredients (APIs) and other fine chemicals.
• Agrochemical Synthesis: Employed in the production of herbicides, pesticides, and plant growth regulators.
• Solvent and Chemical Intermediate: Serves as a solvent for resins and gums and as a starting material for plasticizers, stabilizers, and other polymer additives.
• Animal Feed Additive: Used in the production of salts (e.g., calcium isobutyrate) that act as preservatives and mold inhibitors in silage and feed.
• Research & Development: Utilized in laboratories as a reagent for organic synthesis and biochemical research.

Quality Control

Our Isobutyric Acid is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, identity, and impurity profiles. Certificates of Analysis (COA) documenting results for assay, water content, and other critical parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources, strong bases, and oxidizing agents. Recommended storage temperature is between 15°C and 25°C. As a strong acid/organic solvent, ensure containers are kept upright to prevent leakage and are clearly labeled.
