3-(n-(4-Ethoxyphenyl)sulfamoyl)-4-methylbenzoic acid CAS 406927-80-8 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 3-(n-(4-Ethoxyphenyl)sulfamoyl)-4-methylbenzoic acid.

3-(n-(4-Ethoxyphenyl)sulfamoyl)-4-methylbenzoic acid (CAS 406927-80-8) is a high-purity analytical reference standard with the molecular formula C16H17NO5S and a molecular weight of 335.37 g/mol.

Structurally, 3-(n-(4-Ethoxyphenyl)sulfamoyl)-4-methylbenzoic acid (C16H17NO5S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 335.37 g/mol, it falls into the moderately-high-molecular-weight range. 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), 3-(n-(4-Ethoxyphenyl)sulfamoyl)-4-methylbenzoic acid 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.
