Linagliptin Impurity 53 CAS 188111-79-7

Description

Compared with other compounds in its class, the molecular weight of 200.28 g/mol gives Linagliptin Impurity 53 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Linagliptin Impurity 53 (CAS 188111-79-7), a pharmacopoeial impurity reference standard (molecular formula C10H20N2O2, MW 200.28 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Linagliptin Impurity 53 (C10H20N2O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 200.28 g/mol, it falls into the medium-molecular-weight range. 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), Linagliptin Impurity 53 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.
