3-Amino-4-chloro-N,N-diethylbenzene-1-sulfonamide CAS 71794-12-2

Description

Compared with other compounds in its class, the molecular weight of 262.76 g/mol gives 3-Amino-4-chloro-N,N-diethylbenzene-1-sulfonamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-Amino-4-chloro-N,N-diethylbenzene-1-sulfonamide (CAS 71794-12-2), molecular formula C10H15ClN2O2S and molecular weight 262.76 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 3-Amino-4-chloro-N,N-diethylbenzene-1-sulfonamide (C10H15ClN2O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 262.76 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
