Salmeterol Impurity 17 CAS 94749-00-5

Description

Compared with other compounds in its class, the molecular weight of 325.49 g/mol gives Salmeterol Impurity 17 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Salmeterol Impurity 17 (CAS 94749-00-5) is a certified pharmaceutical impurity reference standard with the molecular formula C22H31NO and a molecular weight of 325.49 g/mol.

Based on its molecular formula C22H31NO, Salmeterol Impurity 17 contains a steroid 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 325.49 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), Salmeterol Impurity 17 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.
