For chemists, formulators, and safety officers, a thorough understanding of a chemical's properties and safe handling procedures is non-negotiable. 4-Fluorobenzyl Bromide (CAS 459-46-1), a valuable reagent in organic synthesis, possesses specific characteristics that dictate its storage, use, and safety precautions. This guide aims to provide essential information for those working with this compound, whether in a research laboratory or an industrial manufacturing setting.

Physically, 4-Fluorobenzyl Bromide is typically described as a colorless to yellow liquid. While specific melting points can vary based on purity, it generally remains liquid at standard room temperatures, with a reported melting point around -3.66°C. Its boiling point is approximately 85°C at 15 mmHg, indicating moderate volatility. The density is around 1.517 g/mL at 25°C, making it denser than water. These physical attributes are important for chemists when designing reaction setups or planning storage solutions.

Chemically, 4-Fluorobenzyl Bromide is a potent alkylating agent. The presence of the bromine atom makes the benzylic carbon electrophilic, readily undergoing nucleophilic substitution (SN2 reactions). This reactivity is precisely why it's sought after for introducing the 4-fluorobenzyl group. However, this reactivity also implies that it can be corrosive and irritating. Safety data sheets (SDS) typically classify it with hazard statements like H314 (Causes severe skin burns and eye damage) and H318 (Causes serious eye damage). Therefore, proper personal protective equipment (PPE) is crucial when handling it, including chemical-resistant gloves, eye protection (goggles or face shield), and protective clothing.

When considering storage, 4-Fluorobenzyl Bromide should be kept in a cool, dry, well-ventilated area, away from incompatible materials such as strong oxidizing agents, strong bases, and moisture. Containers should be tightly sealed to prevent degradation or reaction with the atmosphere. For bulk purchases, understanding the recommended storage conditions from the manufacturer or supplier is essential for maintaining product integrity and ensuring safety. If you are looking to buy this product, always inquire about the latest safety guidelines and SDS from your supplier.

In summary, while 4-Fluorobenzyl Bromide (CAS 459-46-1) is an exceptionally useful compound for synthesis, its handling requires diligence and adherence to safety protocols. Understanding its properties, from physical state to chemical reactivity, and implementing appropriate safety measures will ensure its effective and secure use in any chemical application.
