Sivelestat Impurity 14 Triethylamine salt CAS CATO-C4X-212314

Description

Compared with other compounds in its class, the molecular weight of 359.48 g/mol gives Sivelestat Impurity 14 Triethylamine salt distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Sivelestat Impurity 14 Triethylamine salt (CAS CATO-C4X-212314), a pharmacopoeial impurity reference standard (molecular formula C11H14O5SC6H15N, MW 359.48 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C11H14O5SC6H15N, Sivelestat Impurity 14 Triethylamine salt contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 359.48 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), Sivelestat Impurity 14 Triethylamine salt 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.
