Description

Compared with other compounds in its class, the molecular weight of 367.78 g/mol gives 2-Chloro-4-(4-(3-nitrophenyl)buta-1,3-dien-1-yl)benzene-1-sulfonyl fluoride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 2-Chloro-4-(4-(3-nitrophenyl)buta-1,3-dien-1-yl)benzene-1-sulfonyl fluoride (CAS 31368-36-2), a certified reference material (molecular formula C16H11ClFNO4S, MW 367.78 g/mol) for analytical method development and quality control.

Based on its molecular formula C16H11ClFNO4S, 2-Chloro-4-(4-(3-nitrophenyl)buta-1,3-dien-1-yl)benzene-1-sulfonyl fluoride contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 367.78 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.
