Chemical Structure

2-(n-Methyl4-fluorobenzenesulfonamido)ethane-1-sulfonyl fluoride CAS 877964-15-3 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(n-Methyl4-fluorobenzenesulfonamido)ethane-1-sulfonyl fluoride.

CATO supplies 2-(n-Methyl4-fluorobenzenesulfonamido)ethane-1-sulfonyl fluoride (CAS 877964-15-3), a certified reference material (molecular formula C9H11F2NO4S2, MW 299.31 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, 2-(n-Methyl4-fluorobenzenesulfonamido)ethane-1-sulfonyl fluoride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 299.31 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
