1. Product Overview

Propionic Acid (CAS No. 79-09-4) is a widely used short-chain organic acid known for its strong anti-mold and anti-bacterial performance, especially in high-moisture environments. It is commonly used in animal feed preservation, grain storage protection, and as an important intermediate in chemical manufacturing.

Our company supplies high-purity propionic acid (≥99.5%) with stable batch quality, full traceability, and documentation aligned with major international standards. As a regulated hazardous liquid, all shipments are handled in compliance with IMDG, ADR, and IATA transport requirements to ensure safe global delivery.

Note:
Propionic acid is generally supplied as an industrial raw material. In food applications, it is usually converted into approved preservatives such as calcium propionate or sodium propionate. In feed and grain protection, propionic acid may be used directly depending on local regulations.

Key Advantages

High purity liquid propionic acid (≥99.5%)
Low water and aldehyde content
Stable supply from controlled production facilities
Full documentation available: TDS, SDS, COA (each batch)
Flexible supply from trial quantity to bulk container shipment
Experienced in global hazardous liquid export logistics. As the high-purity precursor for our Propionates Series, our Propionic Acid 99.5% ensures consistent quality for downstream salts like Calcium Propionate.
