Tenoxicam EP Impurity B CAS 59804-25-0

Description

Compared with other compounds in its class, the molecular weight of 275.30 g/mol gives Tenoxicam EP Impurity B distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

As a process- or degradation-related impurity, Tenoxicam EP Impurity B (CAS 59804-25-0, C9H9NO5S2) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Tenoxicam EP Impurity B is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 275.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

As a certified reference material (CRM), Tenoxicam EP Impurity B 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.
