Understanding Phthaloyl Dichloride (CAS 88-95-9): Properties and Safe Handling
For professionals in the chemical and pharmaceutical industries, a deep understanding of a compound's properties and safe handling procedures is fundamental to successful and secure operations. Phthaloyl Dichloride (CAS 88-95-9) is a prime example of a versatile chemical intermediate that, while highly useful, requires informed management due to its inherent reactivity.
Phthaloyl Dichloride, a derivative of phthalic acid, is an organic compound with the chemical formula C8H4Cl2O2. Its molecular structure features a benzene ring with two adjacent carbonyl chloride groups. This functional group arrangement makes it a potent acylating agent, readily reacting with nucleophiles. Commonly, it appears as a clear to pale yellow oily liquid, with a pungent odor. Its melting point is typically in the range of 6-12°C, and its boiling point is around 269-271°C. Importantly, Phthaloyl Dichloride is sensitive to moisture and will decompose upon contact with water, releasing hydrochloric acid, which necessitates storage in dry conditions.
The reactivity of Phthaloyl Dichloride is key to its utility. It efficiently participates in acylation reactions with alcohols to form esters and with amines to form amides. This makes it an indispensable intermediate in the synthesis of pharmaceuticals, agrochemicals, and various specialty organic chemicals. Its role as a building block in creating complex molecular structures is well-established, enabling chemists to achieve targeted functionalization. The high purity (often >98%) offered by reliable manufacturers ensures predictable reaction outcomes.
Given its corrosive nature and reactivity, safe handling of Phthaloyl Dichloride is paramount. According to GHS classifications, it is marked with Hazard Statement H314: 'Causes severe skin burns and eye damage.' Consequently, appropriate personal protective equipment (PPE) must always be worn. This includes chemical-resistant gloves, protective clothing, safety goggles, and face shields. Work should ideally be conducted in a well-ventilated area or under a fume hood to prevent inhalation of vapors. Immediate action is required in case of skin or eye contact, involving thorough rinsing with water and seeking medical attention.
Proper storage is also critical for maintaining the integrity and safety of Phthaloyl Dichloride. It should be stored in a cool, dry, and well-ventilated area, away from incompatible materials such as water, alcohols, bases, and oxidizing agents. Containers must be kept tightly sealed to prevent moisture ingress. For businesses looking to purchase Phthaloyl Dichloride, consulting the Safety Data Sheet (SDS) provided by the manufacturer or supplier is essential for detailed handling and emergency procedures.
When procuring this chemical, understanding the nuances of its properties and safety requirements is as important as the Phthaloyl Dichloride price and availability.
