Potassium Persulfate

Potassium Persulfate,

Potassium persulfate is a white, crystalline, inorganic compound commonly used as a strong oxidizing agent, radical initiator, and cleaning/etching agent. It decomposes upon heating or in solution to produce sulfate radicals, making it highly effective in polymerization reactions, surface treatments, and analytical chemistry.

Key Features:

• Chemical Formula: K₂S₂O₈

• Molar Mass: 270.32 g/mol

• Purity: Typically ≥98% (ACS or reagent grade)

• Appearance: White to off-white crystalline powder

• Solubility: Soluble in water, insoluble in alcohol

• Oxidizing Power: Releases free radicals (SO₄⁻•) upon decomposition

• CAS Number: 7727-21-1

Common Applications:

• Polymerization initiator in emulsion and solution polymerizations (e.g., acrylates, styrene)

• Etchant in printed circuit board (PCB) production

• Surface cleaning and etching in electronics and semiconductor industries

• Oxidant in analytical chemistry and wastewater treatment

• Hair bleaching and cosmetic formulations (in controlled concentrations)

• Soil and groundwater remediation via chemical oxidation (ISCO)
