Chemical Safety Concerns of Sulfur Mustard Analog, 2-Chloroethyl Ethyl Sulfide, in Laboratory Study

Sulfur mustard (sm), a classic chemical weapon in the vesicant category, can induce severe damage, for which the therapy is stilllimited even today. laboratory work is essential in unveiling toxicological effects and developing medical countermeasures. sulfurmustard analog 2-chloroethyl ethyl sulfide (cees), is employed in the lab for less toxicity. however, due to its similar characteristicsto sm (being oily, hydrophobic, and volatile), the manipulation of cees still needs special attention to avoid personnel injuryand laboratory pollution. here, to clear the chemical safety concerns in the laboratory study of cees, the working procedure andexperimental data are summarized, which might help educate new researchers to be skilled and professional.
