3-Amino-4-ethoxy-N,N-dimethylbenzene-1-sulfonamide CAS 22121-73-9

Description

3-Amino-4-ethoxy-N,N-dimethylbenzene-1-sulfonamide (CAS 22121-73-9), molecular formula C10H16N2O3S and molecular weight 244.31 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-Amino-4-ethoxy-N,N-dimethylbenzene-1-sulfonamide (C10H16N2O3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

As a certified reference material (CRM), 3-Amino-4-ethoxy-N,N-dimethylbenzene-1-sulfonamide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
