Chemical Structure

4-(Pentafluorosulfur)cinnamic acid CAS 851427-44-6 chemical structure

Description

The occurrence of 4-(Pentafluorosulfur)cinnamic acid is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-(Pentafluorosulfur)cinnamic acid (CAS 851427-44-6), molecular formula C9H7F5O2S and molecular weight 274.21 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C9H7F5O2S, 4-(Pentafluorosulfur)cinnamic acid contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 274.21 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
