C4H10N2O2

C4H10N2O2 is the molecular formula for several organic compounds that share four carbon atoms, two nitrogen atoms, and two oxygen atoms. The formula corresponds to a molar mass of about 118.12 g/mol. The degree of unsaturation is one, indicating that any isomer either contains one ring or one carbonyl group in its structure.

Because the formula allows multiple structural arrangements, C4H10N2O2 encompasses several constitutional isomers. The two nitrogen atoms can be incorporated in various functional motifs, such as amide, hydrazide, or carbamate-type groups, while the single site of unsaturation can arise from a carbonyl function or a ring. Consequently, there is no single defined compound uniquely identified by this formula.

Representative isomer classes include cyclic lactams or carbamate-containing rings, as well as acyclic structures featuring amide and other substituents that satisfy valence requirements. The physical properties of these isomers—such as melting point, boiling point, and polarity—vary widely depending on the precise arrangement of atoms and functional groups. In general, compounds with this formula are expected to be polar and capable of hydrogen bonding due to the presence of two heteroatoms.

Applications and occurrence: Compounds with this formula appear mainly as intermediates in organic synthesis or as examples in discussions of isomerism; none are widely used as a single commercial substance. Safety depends on the specific isomer; handling should follow appropriate chemical-safety guidelines.
