Product Overview
Benzyl bromide (C₇H₇Br) is a high-purity alkylating agent widely used in organic synthesis for its excellent reactivity and selectivity. This clear, colorless liquid features a density of 1.44 g/cm³ and boils at 198°C, ensuring stability under standard lab conditions. With a purity of 99%, it serves as a reliable reagent for introducing benzyl groups in chemical reactions, particularly in the synthesis of pharmaceutical intermediates, fine chemicals, and specialty polymers. Its high reactivity with nucleophiles makes it indispensable for creating carbon-carbon and carbon-heteroatom bonds. The compound is sensitive to moisture and light, requiring storage in a cool, dry place under inert gas to maintain its integrity. Benzyl bromide is compatible with most organic solvents but should be handled with care due to its corrosive nature. For researchers requiring consistent performance, this reagent delivers reproducible results in halogenation, esterification, and coupling reactions. Always use in a well-ventilated fume hood with appropriate personal protective equipment (PPE) to ensure safety.
FAQs
1. What is the shelf life of benzyl bromide when stored properly?
When stored in a tightly sealed container under inert gas at 2-8°C, benzyl bromide maintains its purity for up to 12 months. Avoid exposure to air or moisture to prevent decomposition.
2. Can benzyl bromide be used as a substitute for benzyl chloride in reactions?
Yes, benzyl bromide is often preferred over benzyl chloride due to its higher reactivity in nucleophilic substitution reactions, though reaction conditions may need adjustment for optimal yields.
3. What solvents are compatible with benzyl bromide for dilution?
Benzyl bromide dissolves well in non-polar solvents like dichloromethane, toluene, and diethyl ether. Avoid protic solvents like water or alcohols, which can lead to hydrolysis.
4. How should spilled benzyl bromide be handled in the lab?
Absorb spills immediately with inert materials like sand or vermiculite, then neutralize with a weak base solution (e.g., sodium bicarbonate). Dispose of waste according to local hazardous chemical regulations.
5. Does benzyl bromide require special shipping conditions in India?
Yes, it is classified as a hazardous chemical (UN 1737) and must be shipped in approved containers with proper labeling. Ensure compliance with DGCA and IMDG regulations for air/road transport.
