Nimesulide Impurity 2 CAS 38880-53-4

Description

Compared with other compounds in its class, the molecular weight of 232.21 g/mol gives Nimesulide Impurity 2 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Nimesulide Impurity 2 (CAS 38880-53-4) is a high-purity analytical reference standard with the molecular formula C7H8N2O5S and a molecular weight of 232.21 g/mol.

Nimesulide Impurity 2 (C7H8N2O5S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), Nimesulide Impurity 2 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.
