FAQs

1. What is the solubility of Maleic Acid 99.5% AR in water?

Maleic Acid 99.5% AR is highly soluble in water, with a solubility of approximately 78.8 g/100 mL at 25?C, forming a clear, colorless solution.

2. Can this grade be used for food or pharmaceutical applications?

While Maleic Acid 99.5% AR is of high purity, it is specifically classified as an analytical reagent and not certified for food, pharmaceutical, or clinical use. For such applications, food-grade or USP/EP-compliant variants are recommended.

3. How should Maleic Acid 99.5% AR be stored to maintain stability?

Store in a tightly sealed container in a cool, dry place, away from direct sunlight and moisture. Avoid exposure to alkaline substances or strong oxidizing agents to prevent degradation.

4. Is this product compatible with glass or plastic labware?

Maleic Acid 99.5% AR is compatible with standard borosilicate glass and most laboratory-grade plastics like PP or HDPE. However, prolonged contact with metals or rubber stoppers should be avoided to prevent contamination.

5. What alternatives exist if Maleic Acid is unavailable?

Fumaric Acid or Succinic Acid may serve as structural alternatives in certain reactions, though their reactivity and physical properties differ. Consult protocol-specific requirements before substitution.
