The occurrence of 2,2,2-Trichloroethyl (chloro(methylthio)methylene)sulfamate is closely related to an amide group, a sulfone group, 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-Trichloroethyl (chloro(methylthio)methylene)sulfamate (CAS 882739-48-2) is a high-purity analytical reference standard with the molecular formula C4H5Cl4NO3S2 and a molecular weight of 321.03 g/mol.
Based on its molecular formula C4H5Cl4NO3S2, 2,2,2-Trichloroethyl (chloro(methylthio)methylene)sulfamate contains an amide group, a sulfone group, a carboxylic acid group, 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 321.03 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.
