Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 242.21 g/mol gives Dimethyl (3-phenylpropanoyl)phosphonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Dimethyl (3-phenylpropanoyl)phosphonate (CAS 55339-95-2), a certified reference material (molecular formula C11H15O4P, MW 242.21 g/mol) for analytical method development and quality control.
Structurally, Dimethyl (3-phenylpropanoyl)phosphonate (C11H15O4P) contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.5, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 242.21 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
