2,2,2-Trichloro-2lambda5-benzo[d][1,3,2]dioxaphosphole CAS 2007-97-8

Description

The occurrence of 2,2,2-Trichloro-2lambda5-benzo[d][1,3,2]dioxaphosphole is closely related to organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2,2,2-Trichloro-2lambda5-benzo[d][1,3,2]dioxaphosphole (CAS 2007-97-8) is a high-purity analytical reference standard with the molecular formula C6H4Cl3O2P and a molecular weight of 245.43 g/mol.

Based on its molecular formula C6H4Cl3O2P, 2,2,2-Trichloro-2lambda5-benzo[d][1,3,2]dioxaphosphole contains organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 245.43 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.

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.
