Chemical Structure

Ethyl 3-(N,N-bis(4-methoxybenzyl)sulfamoyl)-1-methyl-1H-pyrazole-5-carboxylate CAS 2281769-53-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 473.54 g/mol gives Ethyl 3-(N,N-bis(4-methoxybenzyl)sulfamoyl)-1-methyl-1H-pyrazole-5-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Ethyl 3-(N,N-bis(4-methoxybenzyl)sulfamoyl)-1-methyl-1H-pyrazole-5-carboxylate (CAS 2281769-53-5), molecular formula C23H27N3O6S and molecular weight 473.54 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Ethyl 3-(N,N-bis(4-methoxybenzyl)sulfamoyl)-1-methyl-1H-pyrazole-5-carboxylate (C23H27N3O6S) is characterized by a flavonoid core, 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), Ethyl 3-(N,N-bis(4-methoxybenzyl)sulfamoyl)-1-methyl-1H-pyrazole-5-carboxylate 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.
