Product Overview
Fumaric acid 98% for synthesis is a high-purity, non-hygroscopic crystalline powder widely used in laboratory and industrial applications. Known for its low solubility in water and high thermal stability, it serves as a key intermediate in organic synthesis, particularly in the production of polyester resins, alkyd resins, and unsaturated polyesters. Its trans-configuration makes it more stable than its cis-isomer (maleic acid), ensuring consistent performance in chemical reactions. The synthesis grade ensures minimal impurities, making it suitable for precise applications like buffer preparation, food acidulants, and pharmaceutical intermediates. With a melting point of approximately 287°C, fumaric acid remains stable under high-temperature conditions, reducing degradation risks during processing. Its role in polymer cross-linking and as a pH regulator further enhances its versatility in research and development settings. Store in a cool, dry place to maintain purity and extend shelf life.
FAQs
1. What is the difference between fumaric acid and maleic acid?
Fumaric acid is the trans-isomer, while maleic acid is the cis-isomer. Fumaric acid is more stable, less soluble in water, and has a higher melting point, making it preferable for synthesis applications.
2. Can this fumaric acid be used in food-grade applications?
This product is labeled for synthesis, not food-grade use. For food applications, ensure compliance with local regulatory standards and opt for food-grade certified fumaric acid.
3. How should fumaric acid be stored to maintain its purity?
Store in a tightly sealed container in a cool, dry place, away from moisture and direct sunlight. Avoid exposure to incompatible substances like strong oxidizing agents.
4. Is fumaric acid compatible with common organic solvents?
Fumaric acid is sparingly soluble in cold water but dissolves in hot water and organic solvents like ethanol, acetone, and dimethylformamide (DMF). Always verify compatibility before use.
5. What safety precautions should be taken when handling fumaric acid?
Wear protective gloves, goggles, and a lab coat to avoid skin and eye contact. Work in a well-ventilated area or under a fume hood, as dust inhalation may cause respiratory irritation.
