Chemical Structure
Description
The molecular framework of 3,4-Dichlorobenzene-1-sulfonyl fluoride (HO3SC3H4ONa) is characterized by a sulfone group, a carboxylic acid group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.
3,4-Dichlorobenzene-1-sulfonyl fluoride (CAS 60191-50-6), molecular formula HO3SC3H4ONa and molecular weight 160.12 g/mol, is a CATO reference standard with documented purity and traceability.
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.
