Description

Propionic Acid is a naturally occurring short-chain carboxylic acid and a key industrial chemical with a pungent odor. It serves as a highly effective preservative and antimicrobial agent, valued for its ability to inhibit the growth of molds, fungi, and certain bacteria. This versatile acid is essential for manufacturers in the food & feed, agriculture, pharmaceutical, and chemical synthesis sectors.

Application

• Food & Feed Preservation: Widely used as a mold inhibitor in baked goods, cheeses, and animal feed (E280).
• Herbicide Intermediate: A crucial precursor in the synthesis of herbicides like dichlorprop and other phenoxy herbicides.
• Pharmaceutical Synthesis: Employed as an intermediate in the production of various pharmaceuticals, including non-steroidal anti-inflammatory drugs (NSAIDs).
• Chemical Manufacturing: Used in the production of propionate esters, plasticizers, solvents, and perfumes.
• Grain & Silage Protection: Applied directly to stored grains and silage to prevent spoilage and mycotoxin formation.
• Cellulose Acetate Propionate (CAP): A key raw material in the manufacture of CAP plastics and coatings.

Quality Control

Our Propionic Acid is produced under a stringent quality management system. We offer grades suitable for food, feed, and industrial applications, with production processes designed to meet relevant standards. Certificates of Analysis (COA) documenting purity, identity, and key parameters are provided with every shipment to ensure traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources, ignition points, and incompatible materials such as strong oxidizers, bases, and alkalis. Due to its corrosive nature and high volatility, containers must be kept upright and sealed when not in use. Recommended storage temperature is between 15°C and 25°C.
