1-Indanone oxime is a sulfonylating agent that reacts with primary amines to produce sulfonylureas. It is a model system for the study of chemical diversity and isozymes. 1-Indanone oxime has been shown to be an efficient synthetic agent for preparing hydroxyl compounds and oxime derivatives, and can be used to synthesize chlorides, secondary amines, and tertiary amines. The reaction time required for this chemical is shorter than other reagents such as sodium hypochlorite or nitrous acid. The reaction solution can be used in the synthesis of hydrochloric acid, nitric acid, chloroform, and vinyl chloride. 1-Indanone oxime has also been used to produce amino acids such as L-tryptophan or L-tyrosine.

N-Carbamoylmaleimide is a maleimide that reacts with amides to form N-hydroxysuccinimidyl esters. It is used as an alternative to succinimidyl esters for the synthesis of cross-linked polymers. The reaction proceeds via a cyclic intermediate, and is catalyzed by metal ions such as iron. The product is stable at room temperature, but decomposes at elevated temperatures. N-Carbamoylmaleimide can be synthesized by the reaction of methylbenzene with ammonia in the presence of sodium hydroxide, followed by dehydration with sulfuric acid. This compound can also be synthesized using a solid phase synthesis technique, which involves reacting an amine with vinyl ether and dimethylformamide in the presence of a carbonylating agent such as dicyclohexylcarbodiimide (DCC).

4-Methoxypyridine-3-sulfonamide is a potent inhibitor of carbonic anhydrase. It is used in the treatment of chronic glaucoma and other diseases that result from increased intraocular pressure, such as iritis, keratitis, or optic neuritis. 4-Methoxypyridine-3-sulfonamide inhibits the activity of all isoforms of human carbonic anhydrase. The inhibition constants for this drug are higher for cytosolic isoforms than for transmembrane isoforms. This drug has a high selectivity for carbonic anhydrase over other enzymes and can be used to distinguish between different types of isoforms.
