1-(2-Chloro-ethylsulfanyl)-1,1,2,2, 2-pentafluoro-ethane CAS 679-75-4

Description

Based on its molecular formula C4H4ClF5S, 1-(2-Chloro-ethylsulfanyl)-1,1,2,2, 2-pentafluoro-ethane contains sulfur-containing functionality, fluorine/chlorine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 214.58 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.

CATO supplies 1-(2-Chloro-ethylsulfanyl)-1,1,2,2, 2-pentafluoro-ethane (CAS 679-75-4), a certified reference material (molecular formula C4H4ClF5S, MW 214.58 g/mol) for analytical method development and quality control.

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.
