The occurrence of 4-Chloro-2-fluoro-3-(methylthio)benzaldehyde is closely related to sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 4-Chloro-2-fluoro-3-(methylthio)benzaldehyde (CAS 2145093-97-4), a certified reference material (molecular formula C8H6ClFOS, MW 204.65 g/mol) for analytical method development and quality control.
Based on its molecular formula C8H6ClFOS, 4-Chloro-2-fluoro-3-(methylthio)benzaldehyde contains sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 204.65 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
