C4H9O3PO

C4H9O3PO is the molecular formula of a phosphorus-containing organic compound associated with the class of phosphate esters. The formula indicates one phosphorus atom, four carbon atoms, nine hydrogens, and three oxygen atoms. Because many structural isomers can share the same formula, C4H9O3PO does not specify a unique compound; possible structures include various butyl-substituted phosphate esters where a butyl alkyl group is linked to a phosphate moiety through an oxygen atom.

In general, phosphate esters derived from alcohols and phosphoric acid have patterns such as R–O–P(=O)(OR')2 or R–O–P(=O)(OH)2, depending on substitution. However, these patterns typically involve four oxygen atoms around phosphorus, so the given formula could represent a subset of such compounds or a closely related phosphorus‑oxygen skeleton with different connectivity. Precise identification requires structural data, such as a structural diagram or SMILES notation.

Molecular mass is approximately 136.1 g/mol. The compound is expected to be moderately polar and, like many phosphate esters, may undergo hydrolysis under acidic or basic conditions, yielding related phosphate and alcohol products. Phosphate esters in general find use as intermediates in organic synthesis and, in some cases, as plasticizers, flame retardants, or lubricants; specific applications depend on the exact structure.

Safety and handling follow general guidelines for organophosphorus compounds. Due to the potential variety of isomers that share the same formula, consult a reliable data source or obtain structural details to determine properties, hazards, and appropriate handling for the exact compound corresponding to C4H9O3PO.
