Chemical Structure
Description
4-(Bromomethyl)-2-fluorothiophene (CAS 1400991-71-0) is a high-purity analytical reference standard with the molecular formula C5H4BrFS and a molecular weight of 195.05 g/mol.
Based on its molecular formula C5H4BrFS, 4-(Bromomethyl)-2-fluorothiophene contains sulfur-containing functionality, fluorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 195.05 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.
