For chemists and laboratory technicians, a thorough understanding of chemical reagents is fundamental to successful experimentation and production. Phenyl Chloroformate (CAS 1885-14-9) is a compound that demands careful attention due to its reactivity and distinct physical characteristics. This article provides a comprehensive overview of its properties and essential handling guidelines for professionals looking to buy this chemical.

Phenyl Chloroformate, with its chemical formula C7H5ClO2 and a molecular weight of 156.57, is typically supplied as a colorless liquid. Its most noticeable characteristic is a strong, pungent odor, which serves as an initial indicator of its presence. Key physical parameters include a density of approximately 1.283 g/cm3, making it denser than water, and a relatively high boiling point of 186.5 °C at standard atmospheric pressure. Its solubility profile is critical; it tends to undergo hydrolysis in water, reacting to form phenol and other compounds, which means it must be stored and handled under anhydrous conditions.

The reactive nature of Phenyl Chloroformate is precisely what makes it valuable in organic synthesis. It acts as an acylating agent, efficiently introducing the phenoxycarbonyl moiety into other molecules. This makes it a sought-after intermediate for creating esters, carbonates, and carbamates. When considering a purchase, it's important to note its hazard symbols, which often indicate high toxicity and corrosive properties, underscoring the need for strict safety protocols.

Safe handling practices are non-negotiable when working with Phenyl Chloroformate. Always use appropriate personal protective equipment (PPE), including chemical-resistant gloves (such as nitrile or neoprene), safety goggles or a face shield, and a lab coat. Work should be conducted in a well-ventilated area, preferably within a fume hood, to mitigate exposure to its strong odor and potential vapors. Storage should be in tightly sealed containers, away from moisture and incompatible materials like strong bases or oxidizing agents.

For buyers procuring Phenyl Chloroformate, seeking information from a trusted manufacturer or supplier regarding specific purity levels and safe handling recommendations is crucial. Understanding these properties ensures efficient utilization and minimizes risks in laboratory or industrial settings. If you are looking to buy this chemical, consult the supplier's Safety Data Sheet (SDS) for detailed hazard information and handling procedures.
