C21H30O5

C21H30O5 is a molecular formula that describes a family of organic compounds rather than a single substance. It denotes a composition of 21 carbon atoms, 30 hydrogen atoms, and 5 oxygen atoms, with a nominal molecular weight of approximately 362.46 g/mol. The formula has seven degrees of unsaturation, indicating the presence of rings and/or multiple bonds within possible structures.

Because many isomers can satisfy this formula, a wide range of structural arrangements is possible. Potential arrangements may include various esters, lactones, ethers, and carbonyl-containing structures, potentially featuring both aliphatic and aromatic subunits. The exact physical properties—such as melting point, boiling point, polarity, and solubility—depend on the specific connectivity and functional groups present.

In chemical databases, C21H30O5 serves as an entry for a set of compounds encountered in natural product research and synthetic chemistry. A concrete substance with this formula is distinguished by additional identifiers, including a structural diagram, an IUPAC name, SMILES or InChI string, and a CAS registry number.

Analytical characterization of a compound with this formula typically employs spectroscopic methods such as NMR, infrared spectroscopy, and mass spectrometry, sometimes complemented by crystallography to determine the exact structure. In short, C21H30O5 is a formula that signals possible chemical diversity and requires structural details to define a specific substance and its properties.
