Product Overview
Benzylamine is a high-purity, colorless to pale yellow liquid with a strong ammonia-like odor, widely recognized for its versatility in laboratory applications. This AR-grade reagent is synthesized through the reduction of benzonitrile or benzaldehyde, ensuring minimal impurities and consistent performance. Its primary structure, featuring a benzene ring attached to an amine group, makes it highly reactive in nucleophilic substitution, condensation, and reductive amination reactions. The compound exhibits excellent solubility in organic solvents like ethanol, ether, and chloroform, while being partially miscible in water. With a boiling point of approximately 185°C and a flash point of 60°C, it requires careful handling under fume hoods due to its corrosive and flammable nature. Benzylamine’s low viscosity and high volatility make it ideal for use in gas chromatography and as a derivatizing agent for analytical techniques. Its hygroscopic properties necessitate storage in tightly sealed containers under inert atmospheres to prevent moisture absorption and degradation. The reagent’s stability under standard laboratory conditions, combined with its ability to form Schiff bases and amides, positions it as a critical building block in fine chemical synthesis.
FAQs
1. What is the shelf life of benzylamine when stored properly?
When stored in a cool, dry place away from direct sunlight and moisture, benzylamine maintains its stability for up to 24 months from the date of manufacture. Always check the container for signs of oxidation or discoloration before use.
2. Can benzylamine be used as a solvent for polar and nonpolar compounds?
Yes, benzylamine’s amphiphilic nature allows it to dissolve a wide range of polar and nonpolar organic compounds, though its solubility profile is more aligned with nonpolar solvents due to the benzene ring’s hydrophobic character.
3. What precautions should be taken when handling benzylamine in a lab?
Wear nitrile gloves, safety goggles, and a lab coat, and always work under a fume hood due to its corrosive vapors. Avoid contact with skin or eyes, and neutralize spills with dilute acetic acid before cleanup.
4. Is benzylamine compatible with glass or plastic labware?
It is compatible with borosilicate glass but may degrade certain plastics like polyethylene over prolonged exposure. Use PTFE-lined caps for long-term storage to prevent leakage or contamination.
5. How does benzylamine compare to aniline in reactivity?
Benzylamine is generally more nucleophilic than aniline due to the absence of resonance stabilization from the benzene ring to the amine group, making it more reactive in substitution and addition reactions.
