Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 331.52 g/mol gives (E)-Dimethylvinphos distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(E)-Dimethylvinphos (CAS 71363-52-5), molecular formula C10H10Cl3O4P and molecular weight 331.52 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C10H10Cl3O4P, (E)-Dimethylvinphos contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 331.52 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
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.
