Siponimod Impurity 5 CAS 957205-23-1

Description

Compared with other compounds in its class, the molecular weight of 258.28 g/mol gives Siponimod Impurity 5 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Siponimod Impurity 5 (CAS 957205-23-1), a pharmacopoeial impurity reference standard (molecular formula C14H17F3O, MW 258.28 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C14H17F3O, Siponimod Impurity 5 contains a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 258.28 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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), Siponimod Impurity 5 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.
