C20H34O5

C20H34O5 is the molecular formula for organic compounds that contain twenty carbon atoms, thirty-four hydrogen atoms, and five oxygen atoms. As a formula, it represents a family of constitutional isomers and stereoisomers rather than a single substance.

The calculated molecular weight is approximately 354.49 g/mol. By composition, carbon accounts for about 67.7% of the mass, hydrogen for around 9.6%, and oxygen for about 22.6%. The degree of unsaturation (DBE) for this formula is four, implying the presence of four rings and/or pi bonds in the molecule.

With five oxygen atoms, the structure may include carbonyl-containing groups (such as esters, ketones, or hydroxyl-bearing functionalities) as well as ethers or hydroxyl groups. This combination allows several plausible motifs, including lactones, esters, or polyhydroxy ethers, which are common in natural products and synthetic derivatives.

Because many distinct structures can share the same molecular formula, C20H34O5 does not uniquely identify a single compound. Determining the exact structure requires spectroscopic data from techniques such as NMR and mass spectrometry, and, if stereochemistry is relevant, additional chiral analysis.

In chemical databases and literature, C20H34O5 may be cited in the context of formula-based searches, inventory records, or as a descriptor for a class of oxygenated hydrocarbons. Specific identity and properties depend on the actual arrangement of atoms and the resulting functional groups.
