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.
2-((2-Bromoethyl)disulfaneyl)ethan-1-ol (CAS 113398-38-2), molecular formula C4H9BrOS2 and molecular weight 217.15 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C4H9BrOS2, 2-((2-Bromoethyl)disulfaneyl)ethan-1-ol contains sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 217.15 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.
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.
