Product Overview
Furfuraldehyde LR, also known as 2-furaldehyde, is a high-purity laboratory reagent widely used in organic synthesis and as a solvent in various chemical processes. This colorless to pale yellow liquid exhibits a characteristic almond-like odor and a boiling point of 161.7°C, making it a versatile component in laboratory settings. Its molecular formula, C5H4O2, ensures consistent reactivity, which is critical for reproducible experimental results. The LR grade designation guarantees a high level of purity, minimizing impurities that could interfere with sensitive reactions. Furfuraldehyde is particularly valued for its role as a precursor in the production of furan derivatives, resins, and other specialty chemicals. Its solubility in organic solvents and partial miscibility in water further enhance its utility across a broad spectrum of applications. When stored in a cool, dry place away from direct sunlight and incompatible substances, Furfuraldehyde LR maintains its stability and efficacy, ensuring long-term reliability for laboratory use. Proper handling with standard lab safety protocols is recommended to maximize its performance and shelf life.
FAQs
1. What is the shelf life of Furfuraldehyde LR when stored under ideal conditions?
When stored in a tightly sealed container in a cool, dry place away from direct sunlight and moisture, Furfuraldehyde LR typically retains its stability for up to 24 months from the date of manufacture. Regularly check for any signs of degradation such as color changes or sediment formation before use.
2. Is Furfuraldehyde LR compatible with plastic containers for long-term storage?
Furfuraldehyde LR is best stored in glass containers as it can react with certain plastics over time, leading to contamination or degradation. Use amber glass bottles with PTFE-lined caps for optimal storage conditions to preserve its purity and prevent evaporation.
3. Can Furfuraldehyde LR be used as a substitute for formaldehyde in fixation processes?
While both are aldehydes, Furfuraldehyde LR and formaldehyde have distinct chemical properties and reactivities. Furfuraldehyde is not typically recommended as a direct substitute for formaldehyde in fixation processes, as it may not provide the same preservation or cross-linking efficiency. Always consult protocol-specific guidelines before substitution.
4. What precautions should be taken when handling Furfuraldehyde LR in the lab?
Furfuraldehyde LR should be handled in a well-ventilated fume hood due to its volatile nature and potential respiratory irritant properties. Wear appropriate personal protective equipment, including nitrile gloves, safety goggles, and a lab coat. Avoid skin contact, inhalation, and ingestion, and ensure proper disposal according to local chemical waste regulations.
5. How does the LR grade of Furfuraldehyde differ from technical or industrial grades?
The LR (Laboratory Reagent) grade of Furfuraldehyde is specifically purified to meet stringent laboratory standards, ensuring minimal impurities and consistent performance in analytical and synthetic applications. In contrast, technical or industrial grades may contain higher levels of impurities, making them suitable only for non-critical processes where purity is less critical.
