Carbodiimide

<p>In <a href="/facts/Organic_chemistry/djxhxaNg">organic chemistry</a>, a carbodiimide (systematic IUPAC name: methanediimine) is a <a href="/facts/Functional_group/GXkSPsjM">functional group</a> with the formula RN=C=NR. On <a href="/facts/Earth/HLLmDfj0">Earth</a> they are exclusively synthetic, but in <a href="/facts/Interstellar_space/R3LRKyFs">interstellar space</a> the parent compound HN=C=NH has been detected by its <a href="/facts/Maser/yqdMpoDv">maser</a> emissions.
</p><p>A well known carbodiimide is <a href="/facts/Dicyclohexylcarbodiimide/AbjRRd61">dicyclohexylcarbodiimide</a>, which is used in <a href="/facts/Peptide_synthesis/Upd4aqKa">peptide synthesis</a>. Dialkylcarbodiimides are stable. Some diaryl derivatives tend to convert to <a href="/facts/Dimer_(chemistry)/mU64PnEq">dimers</a> and <a href="/facts/Polymers/eF32E50K">polymers</a> upon standing at room temperature, though this mostly occurs with low melting point carbodiimides that are liquids at room temperature. Solid diaryl carbodiimides are more stable, but can slowly undergo <a href="/facts/Hydrolysis/JTvwIHPs">hydrolysis</a> in the presence of water over time.
