C8H16O4

C8H16O4 is the molecular formula for eight carbons, sixteen hydrogens, and four oxygens. As a formula, it does not identify a single substance; many constitutional isomers share this formula.

These isomers can belong to several classes, most commonly esters and lactones, but also other oxygen-containing derivatives such as hydroxy esters or cyclic esters. Depending on the arrangement, compounds with this formula may have different physical properties, including melting and boiling points, volatility, and polarity.

Molar mass is approximately 176.21 g/mol.

Because C8H16O4 encompasses multiple structures, specific applications or hazards are determined by the particular isomer. Some esters and lactones are used as solvents, plasticizers, or flavors and fragrances, but any such use would refer to a specific compound rather than the abstract formula.

In chemical databases, C8H16O4 is treated as a formula entry that can correspond to many structural possibilities; researchers determine identity by spectroscopic data and structural analysis.

Safety notes: handle unknown organic liquids with standard lab precautions; consult the material safety data sheet for the precise compound.
