Chemical Structure

Phenylphosphonic acid diethyl CAS 1754-49-0 chemical structure

Description

As a certified reference material (CRM), Phenylphosphonic acid diethyl meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

Phenylphosphonic acid diethyl (CAS 1754-49-0), molecular formula C10H15O3P and molecular weight 214.20 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, Phenylphosphonic acid diethyl (C10H15O3P) contains a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.5, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 214.20 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.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
