Chemical Structure

5-Fluoro-2-(2-methoxyethoxy)benzene-1-sulfonyl chloride CAS 1174295-58-9 chemical structure

Description

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.

5-Fluoro-2-(2-methoxyethoxy)benzene-1-sulfonyl chloride (CAS 1174295-58-9) is a high-purity analytical reference standard with the molecular formula C9H10ClFO4S and a molecular weight of 268.69 g/mol.

5-Fluoro-2-(2-methoxyethoxy)benzene-1-sulfonyl chloride (C9H10ClFO4S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
