Formoterol Impurity 58 CAS 725719-13-1

Description

Compared with other compounds in its class, the molecular weight of 358.44 g/mol gives Formoterol Impurity 58 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Formoterol Impurity 58 (CAS 725719-13-1) is a certified pharmaceutical impurity reference standard with the molecular formula C20H26N2O4 and a molecular weight of 358.44 g/mol.

Based on its molecular formula C20H26N2O4, Formoterol Impurity 58 contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 358.44 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), Formoterol Impurity 58 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.
