Benzoyl Chloride, a compound with the CAS number 98-88-4, is a fundamental building block in the chemical industry, renowned for its unique properties and broad applicability. As a colorless, fuming liquid with a sharp, irritating odor, it demands careful consideration regarding its handling and application. This article aims to elucidate the core chemical properties and essential safety protocols associated with Benzoyl Chloride, ensuring its effective and secure utilization in various manufacturing processes.

Physically, Benzoyl Chloride is a liquid at room temperature, typically appearing colorless, though industrial grades may exhibit a slight yellowish tint. Its molecular formula is C7H5ClO, and it possesses a molecular weight of 140.57 g/mol. A key characteristic is its reactivity, particularly its tendency to react with moisture to form benzoic acid and hydrochloric acid, a process that releases corrosive fumes. This sensitivity to water underscores the importance of anhydrous conditions during its storage and use. Understanding these physical and chemical properties is crucial for anyone looking to purchase Benzoyl Chloride for their operations.

Chemically, Benzoyl Chloride is classified as an acyl chloride, making it a potent acylating agent. It readily reacts with nucleophiles such as alcohols, amines, and even water, forming esters, amides, and benzoic acid, respectively. This reactivity is leveraged extensively in organic synthesis, including Friedel-Crafts acylation reactions to produce benzophenones and other valuable aromatic ketones. The efficiency of these reactions contributes to the compound's widespread use. When considering the purchase of Benzoyl Chloride, its reaction profile is a primary factor in determining its suitability for specific synthesis pathways.

The hazardous nature of Benzoyl Chloride necessitates stringent safety measures. It is labeled as corrosive and is harmful if swallowed, inhaled, or comes into contact with skin. It can cause severe skin burns and eye damage, and its vapors are highly irritating to the respiratory tract. Therefore, protective gear, including chemical-resistant gloves, safety goggles, and respiratory protection, is mandatory when handling this substance. Proper ventilation in work areas is also critical. Manufacturers like NINGBO INNO PHARMCHEM CO.,LTD. provide comprehensive Safety Data Sheets (SDS) that detail these risks and the recommended protective measures, guiding users on how to safely buy and use Benzoyl Chloride.

Industrial applications of Benzoyl Chloride are vast, ranging from the production of dyes, perfumes, and pharmaceuticals to its use as an initiator in polymer manufacturing. In the pharmaceutical sector, for example, it is a key intermediate for synthesizing various drug compounds. The agrochemical industry utilizes it in the creation of pesticides and herbicides, while the textile industry employs it in dye synthesis and fiber treatment. The consistent demand for Benzoyl Chloride across these sectors reinforces its status as an essential industrial chemical.

In conclusion, Benzoyl Chloride (CAS 98-88-4) is a highly reactive and versatile chemical intermediate. Its chemical properties, while enabling a wide range of synthesis applications, also mandate a strong focus on safety. By understanding its characteristics and adhering to strict handling protocols, industries can effectively leverage the power of Benzoyl Chloride in their production processes. Responsible sourcing and diligent safety practices are key to harnessing the benefits of this vital compound.
