Chemical Structure
Description
The occurrence of 2-Methoxy-5-(pentafluoro-lambda6-sulfanyl)benzenesulfonyl chloride is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-Methoxy-5-(pentafluoro-lambda6-sulfanyl)benzenesulfonyl chloride (CAS 1706447-05-3) is a high-purity analytical reference standard with the molecular formula C7H6ClF5O3S2 and a molecular weight of 332.70 g/mol.
Structurally, 2-Methoxy-5-(pentafluoro-lambda6-sulfanyl)benzenesulfonyl chloride (C7H6ClF5O3S2) contains 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 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 332.70 g/mol, it falls into the moderately-high-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.
