Benzyl chloride (CAS# 100-44-7) is a fascinating compound that plays a significant role in various chemical processes. With its molecular formula C7H7Cl and a molecular weight of 126.58 g/mol, this colorless to slightly yellow liquid has distinct characteristics that make it both useful and hazardous.
One striking feature of benzyl chloride is its pungent odor—an irritating scent that serves as an important reminder of the need for caution when handling it. The boiling point sits at around 179 °C while the melting point dips down to -39 °C, indicating its volatility under certain conditions. It’s also worth noting that benzyl chloride has a density of approximately 1.1 g/mL at room temperature.
When discussing safety, benzyl chloride requires careful consideration due to its potential health risks. Exposure limits are set at TLV-TWA 1 ppm (around 5 mg/m3), with an IDLH value of 10 ppm according to NIOSH guidelines. Interestingly, while animal studies suggest limited evidence for carcinogenicity in humans (classified as IARC Group 2A), it's essential always to treat this substance with respect due to possible harmful effects on health.
In terms of storage and stability, keeping benzyl chloride below +30°C is crucial since it can decompose upon contact with water or strong oxidizing agents—a reaction producing toxic fumes that could pose serious dangers in poorly ventilated areas.
The applications for benzyl chloride are diverse; from serving as an intermediate in organic synthesis to being utilized in the production of pharmaceuticals and fragrances—it’s clear why chemists often turn their attention toward this compound.
Moreover, suppliers like Sigma-Aldrich provide comprehensive Safety Data Sheets (SDS) detailing hazard statements such as H302 (harmful if swallowed) and H318 (causes serious eye damage). These documents serve not only as regulatory requirements but also vital resources ensuring safe handling practices across laboratories worldwide.
As we navigate through discussions about chemicals like benzyl chloride, understanding their properties along with associated risks becomes paramount—not just for those working directly with them but also for anyone interested in chemistry's broader implications.
