Linagliptin Impurity 92 D-lactate CAS 168749-30-2(free base)

Description

Compared with other compounds in its class, the molecular weight of 218.25 g/mol gives Linagliptin Impurity 92 D-lactate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Linagliptin Impurity 92 D-lactate (CAS 168749-30-2(free base)), a pharmacopoeial impurity reference standard (molecular formula C6H12N2OC3H6O3, MW 218.25 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Linagliptin Impurity 92 D-lactate (C6H12N2OC3H6O3) 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 218.25 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

CATO manufactures Linagliptin Impurity 92 D-lactate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
