Compared with other compounds in its class, the molecular weight of 251.65 g/mol gives 6-(Trifluoromethyl)pyridine-3-sulfonyl chloride 959996-58-8 C6H3ClF3NO2S Y4858 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

6-(Trifluoromethyl)pyridine-3-sulfonyl chloride 959996-58-8 C6H3ClF3NO2S Y4858 (CAS 959996-58-8) is a high-purity analytical reference standard with the molecular formula C6H9ClF3NO2S and a molecular weight of 251.65 g/mol.

Structurally, 6-(Trifluoromethyl)pyridine-3-sulfonyl chloride 959996-58-8 C6H3ClF3NO2S Y4858 (C6H9ClF3NO2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 251.65 g/mol, it falls into the medium-molecular-weight range. 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.
