2,5-Dichloro-N-{[3-(2-chlorophenyl)-1,2-oxazol-5-yl]methyl}benzene-1-sulfonamide CAS 343372-70-3

Description

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 2,5-Dichloro-N-{[3-(2-chlorophenyl)-1,2-oxazol-5-yl]methyl}benzene-1-sulfonamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 417.69 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

2,5-Dichloro-N-{[3-(2-chlorophenyl)-1,2-oxazol-5-yl]methyl}benzene-1-sulfonamide (CAS 343372-70-3), molecular formula C16H11Cl3N2O3S and molecular weight 417.69 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.
