Chemical Structure

1,2,2,2-Tetrachloroethyl Phosphorodichloridate CAS 41998-91-8 chemical structure

Description

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.

1,2,2,2-Tetrachloroethyl Phosphorodichloridate (CAS 41998-91-8), molecular formula C2HCl6O2P and molecular weight 300.72 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1,2,2,2-Tetrachloroethyl Phosphorodichloridate (C2HCl6O2P) contains organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of -0.5, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 300.72 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
