Linagliptin Impurity 48 CAS 853029-57-9

Description

Compared with other compounds in its class, the molecular weight of 453.29 g/mol gives Linagliptin Impurity 48 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Linagliptin Impurity 48 (CAS 853029-57-9), a pharmacopoeial impurity reference standard (molecular formula C20H17BrN6O2, MW 453.29 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C20H17BrN6O2, Linagliptin Impurity 48 contains a steroid core, an amide group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 453.29 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), Linagliptin Impurity 48 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.
