What is PAA?
Peracetic acid (PAA) is a strong oxidative chemical compound belonging to the organic peroxyacid class, containing a peroxy functional group attached to an acetyl group. Its chemical formula is represented as CH₃COOOH or C₂H₄O₃. Although PAA is commonly present in equilibrium formulations in practical products, it should not be considered merely as a “mixture of acetic acid and hydrogen peroxide”; it is a distinct peroxyacid molecule with its own molecular structure, CAS number and chemical identity.
Commercial peracetic acid products are generally prepared as balanced formulations consisting of peracetic acid, hydrogen peroxide, acetic acid, water and stabilizers. This equilibrium system directly affects the active PAA concentration, stability, storage behavior and application performance. Therefore, product selection should not be based solely on the percentage of PAA; application area, target ppm, contact time, organic load, material compatibility and active PAA verification method should also be evaluated together.

Molecular Structure Area
The peroxide bond is a key structural feature behind the oxidative character of PAA.
Technical Approach
Correct product selection in PAA applications should be evaluated according to process type, target active PAA level, organic load, contact time, surface or system structure and the need for test kit verification.
