Tenoxicam EP Impurity C CAS 39880-77-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 141.19 g/mol gives Tenoxicam EP Impurity C distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Tenoxicam EP Impurity C (CAS 39880-77-8) is a certified pharmaceutical impurity reference standard with the molecular formula C6H7NOS and a molecular weight of 141.19 g/mol.

Based on its molecular formula C6H7NOS, Tenoxicam EP Impurity C contains an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 141.19 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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 C 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.
