2-(2-Chloroethoxy)ethylphosphonic Acid (CAS 69404-51-9), molecular formula C4H10ClO4P and molecular weight 188.55 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(2-Chloroethoxy)ethylphosphonic Acid (C4H10ClO4P) is characterized by a carbohydrate-derived structure, a phosphate ester group, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
