phthalimidoperoxyhexanoic acid

Basic Information

• CAS Number: 128275-31-6
• Molecular Formula:  C14​H15​NO5​
• Molecular Weight: 277.27 g/mol
• Appearance: White to off-white crystalline powder or granular solid
• Odor: Slight characteristic odor (faint ester or peroxide smell)

Physicochemical Properties

• Solubility: Slightly soluble in water, soluble in polar organic solvents such as ethanol, acetone, ethyl acetate, and dimethylformamide (DMF).
• Stability: Stable under cool, dry, and sealed conditions; decomposes when exposed to heat, strong acids, strong bases, or reducing agents. Avoid contact with heavy metal ions.
• Melting Point: Approximately 90-94°C (decomposes during melting)
• Peroxide Content: Typically 9-11% (active oxygen content), a key indicator of its oxidizing activity.

Key Characteristics & Applications

• Core Function: A mild, selective organic peroxide oxidizing agent with low irritation and good compatibility.
• Detergent & Cleaning Industry: Widely used as a bleaching and stain-removing component in laundry detergents, especially for colored fabrics. It bleaches at low temperatures (30-60°C) without damaging fabric fibers or fading colors.
• Cosmetics & Personal Care: Utilized in teeth-whitening products (e.g., toothpastes, whitening strips) due to its ability to gently break down stains on tooth enamel without excessive abrasion.
• Organic Synthesis: Serves as an oxidant in chemical reactions, such as the oxidation of alcohols to aldehydes/ketones, and the oxidation of sulfides to sulfoxides. It offers high selectivity and mild reaction conditions.

Safety & Handling

• Hazards: May cause mild skin/eye irritation; avoid direct contact. Decomposes when heated, releasing oxygen and potentially flammable vapors. Not combustible itself but can intensify combustion of organic materials.
• Storage Requirements: Store in a cool, dry, well-ventilated area (temperature <30°C). Keep away from heat, open flames, reducing agents, and strong acids/bases. Seal tightly to prevent moisture absorption and decomposition.
• Protective Measures: Wear gloves, goggles, and a dust mask during handling. Avoid inhalation of dust or aerosols.
