FAQ

What is Phthalic Acid Potassium Salt (CAS: 877-24-7)?

Phthalic Acid Potassium Salt (CAS: 877-24-7) is a white crystalline powder with the chemical formula C8H5KO4. It is derived from phthalic acid and potassium hydroxide, commonly used as a precursor in chemical synthesis. This compound is soluble in water and organic solvents, and exhibits acidic properties due to its phthalate structure.

What are the main uses of Phthalic Acid Potassium Salt (CAS: 877-24-7)?

Phthalic Acid Potassium Salt (CAS: 877-24-7) is widely used in pharmaceuticals for drug synthesis, in the plastics industry as a component in polyurethanes, and in the production of dyes and pigments. It also serves as an acidifier in food additives and a reagent in research for organic chemistry applications.

Is Phthalic Acid Potassium Salt (CAS: 877-24-7) safe?

Phthalic Acid Potassium Salt (CAS: 877-24-7) is generally safe when handled properly. However, it can cause skin and eye irritation. Safety guidelines recommend using protective gloves, goggles, and ensuring adequate ventilation. It is not classified as highly toxic but should be avoided in large quantities to prevent adverse health effects.

How should Phthalic Acid Potassium Salt (CAS: 877-24-7) be stored?

Phthalic Acid Potassium Salt (CAS: 877-24-7) should be stored in a cool, dry place, away from direct light and moisture. Keep in a sealed, airtight container to maintain stability. It is chemically stable under normal conditions but should be stored separately from strong acids or oxidizing agents to prevent degradation.
