The principle of Le Chatelier was used in demonstrating that 3-chloro-4,4-dimethyl-2-oxazolidinone (compound 1) itself kills Staphylococcus aureus rather than the very small amount of free chlorine in hydrolysis equilibrium with compound 1. On the other hand, when the N-bromo analog of compound 1 (compound 1B) was used as the disinfectant, the mixture of combined compound 1B and free bromine formed in the hydrolysis equilibrium provided disinfection. When the hydrolysis equilibrium for 1B was suppressed to the level at which a negligible amount of free bromine remained in solution, combined compound 1B was much more efficacious than combined compound 1 at killing S. aureus.
勒夏特列原理被用于证明3-氯-4,4-二甲基-2-恶唑烷酮（化合物1）本身就能杀死金黄色葡萄球菌，而不是与化合物1处于水解平衡状态的极少量游离氯。另一方面，当化合物1的N-溴类似物（化合物1B）用作消毒剂时，在水解平衡中形成的结合态化合物1B和游离溴的混合物起到了消毒作用。当1B的水解平衡被抑制到溶液中残留的游离溴量可忽略不计的水平时，结合态化合物1B在杀死金黄色葡萄球菌方面比结合态化合物1更有效。
