<p>Hydrazine sulfate-15N2 is a trimethylsilylated hydrazine sulfate. It is used as an intermediate for the synthesis of N-trimethylsilylhydrazines and other trimethylsilylhydrazines. The compound can also be used to prepare glutamine as it reacts with dl-glutamine to form hydroxylamine, which then reacts with hydrogen sulfide to form glutathione. Hydrazine sulfate-15N2 is mainly used as a catalyst in the production of nitric acid from ammonia and oxygen gas.</p>

<p>Dideuterosulfuric acid is a protonated molecule that is found in the tropone class of organic compounds. It has been shown to have optical properties similar to those of ferrocene, which is why it is often used as a replacement for this compound. Dideuterosulfuric acid has been studied extensively using a kinetic method with the goal of determining its mechanism and rate constants. Hydroxyl groups are found on the molecule's trifluoroacetic acid side chains, which may contribute to its reactivity with chloride ions and nitrogen atoms. Electrophotographic measurements show that hydrogen bonding occurs between molecules in dilute solutions.</p>
