Salts or esters of sulfonic acids are called sulfonates. Some examples of anionic surfactants are carboxylates, phosphates, sulfates, and sulfonates. These include carboxylates, phosphates, sulfates, and sulfonates. Alkyl sulfonates are esters of alkane sulfonic acids with the general formula R-SO-O-R'. As sulfonic acids tend to be strong acids, the corresponding sulfonates are weak bases. It is a cell cycle non-specific alkylating antineoplastic agent, in the class of alkyl sulfonates. The electrophilic carbocations react with bisulfite ions (HSO)to give sulfonates. Overall, phenacyl PPGs can be used to protect sulfonates, phosphates, carboxylates and carbamates. Polystyrene sulfonates release sodium or calcium ions in the stomach in exchange for hydrogen ions. Suitable leaving groups (X) include iodide, bromide, or sulfonates. Many naphthalenesulfonic acids and sulfonates are useful. Polystyrene sulfonates are useful because of their ion exchange properties. Polystyrene sulfonates are a group of medications used to treat high blood potassium. Many useful compounds and even some biochemicals feature sulfonates. LAS replaced branched dodecylbenzene sulfonates, which were phased out because they biodegrade more slowly.
