Product Overview
Benzaldehyde 99% AR is a high-purity, colorless liquid with a distinct almond-like aroma, widely recognized for its versatility in laboratory and industrial applications. This analytical reagent (AR) grade ensures minimal impurities, making it suitable for precise chemical reactions, synthesis, and research. Its molecular structure (C₇H₆O) features a benzene ring with an aldehyde functional group, contributing to its reactivity and solubility in organic solvents. Benzaldehyde serves as a key intermediate in the production of pharmaceuticals, agrochemicals, and fragrances, while its role in Schiff base formation and condensation reactions makes it indispensable in organic chemistry. The 99% purity level guarantees consistent performance, reducing variability in experimental results. Its low boiling point (178°C) and miscibility with ethanol and ether further enhance its utility in extractions and derivatization processes. Stored in airtight containers away from direct sunlight and oxidizing agents, this reagent maintains stability and potency over extended periods. Whether used as a solvent, reactant, or standard, Benzaldehyde 99% AR delivers reliability for demanding laboratory protocols.
FAQs
1. What is the shelf life of Benzaldehyde 99% AR when stored properly?
When stored in a cool, dry place in tightly sealed containers, Benzaldehyde 99% AR typically retains its purity for 24 months from the date of manufacture. Exposure to air or moisture may accelerate degradation, so ensure minimal headspace in the bottle.
2. Can Benzaldehyde 99% AR be used directly in perfume formulations?
Yes, its high purity and strong almond-like odor make it a common ingredient in perfume and flavor compositions. However, dilution is often required depending on the desired fragrance profile and concentration limits for skin-safe applications.
3. Is this grade of Benzaldehyde compatible with common organic solvents like ethanol or acetone?
Benzaldehyde 99% AR is fully miscible with ethanol, acetone, ether, and most organic solvents. This compatibility makes it ideal for reaction mixtures, extractions, and as a solvent medium in synthetic procedures.
4. What precautions should be taken while handling Benzaldehyde 99% AR?
Handle in a fume hood or well-ventilated area, as vapors can irritate the respiratory tract. Wear nitrile gloves, safety goggles, and a lab coat to avoid skin contact. In case of spillage, absorb with inert material and dispose of as hazardous waste.
5. Are there lower-purity alternatives to Benzaldehyde 99% AR for cost-sensitive applications?
Laboratory-grade (LR) Benzaldehyde, typically 98% pure, is available for less critical applications where minor impurities are acceptable. However, AR grade is recommended for analytical work to ensure accurate and reproducible results.
