Linagliptin Impurity 74 CAS 2434-53-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Linagliptin Impurity 74.

CATO supplies Linagliptin Impurity 74 (CAS 2434-53-9), a pharmacopoeial impurity reference standard (molecular formula C5H7N3O2, MW 141.13 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, Linagliptin Impurity 74 is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 141.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

As a certified reference material (CRM), Linagliptin Impurity 74 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.
