Description

The occurrence of 2-(2-Chloroethoxy)-5,5-bis(hydroxymethyl)-1,3,2-dioxaphosphinane 2-oxide is closely related to a carbohydrate-derived structure, a phosphate ester group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-(2-Chloroethoxy)-5,5-bis(hydroxymethyl)-1,3,2-dioxaphosphinane 2-oxide (CAS 63451-43-4), molecular formula C7H14ClO6P and molecular weight 260.61 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2-(2-Chloroethoxy)-5,5-bis(hydroxymethyl)-1,3,2-dioxaphosphinane 2-oxide (C7H14ClO6P) contains a carbohydrate-derived structure, a phosphate ester group, 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 260.61 g/mol, it falls into the medium-molecular-weight range. 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.

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.
