Product Overview
Fumaric acid LR is a high-purity, crystalline organic compound widely used in laboratory settings for its stability and non-hygroscopic properties. This laboratory reagent-grade fumaric acid ensures consistent results in titrations, buffer solutions, and organic synthesis due to its precise molecular structure and low impurity levels. The compound’s trans-configuration provides higher melting points compared to maleic acid, making it suitable for applications requiring thermal stability. Its white, odorless powder form dissolves moderately in water but is soluble in ethanol, offering versatility in solvent-based reactions. The LR grade designation guarantees adherence to strict quality standards, ensuring reliability in quantitative analyses and research protocols. Store in a cool, dry place in tightly sealed containers to maintain purity and prevent moisture absorption. Ideal for laboratories requiring reproducible outcomes in biochemical and chemical experiments.
FAQs
1. What is the difference between fumaric acid LR and AR grades?
LR (Laboratory Reagent) grade is suitable for general lab applications where high purity is needed but not critical for ultra-sensitive analyses. AR (Analytical Reagent) grade has stricter impurity controls and is used for precise quantitative work.
2. Can this fumaric acid be used for food-grade applications?
No, this LR-grade fumaric acid is specifically formulated for laboratory use and does not meet food-grade certification standards.
3. How should fumaric acid be stored to maintain its shelf life?
Store in an airtight container in a cool, dry place away from direct sunlight and moisture to prevent degradation or clumping.
4. Is fumaric acid compatible with aqueous solutions for buffer preparation?
Yes, it dissolves in water to form a stable solution, making it suitable for buffer systems, though its solubility is moderate compared to other organic acids.
5. What safety precautions should be taken when handling fumaric acid?
Wear protective gloves, goggles, and a lab coat to avoid skin or eye contact. Work in a well-ventilated area, as inhalation of fine particles may cause irritation.
