Chemical Structure
Description
As a certified reference material (CRM), (2-Chloroethyl)phosphonic dichloride 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.
(2-Chloroethyl)phosphonic dichloride (CAS 690-12-0), molecular formula C2H4Cl3OP and molecular weight 181.39 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C2H4Cl3OP, (2-Chloroethyl)phosphonic dichloride contains organophosphorus functionality, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 181.39 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
