Chemical Structure
Description
As a certified reference material (CRM), Lifitegrast Impurity 69 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.
CATO supplies Lifitegrast Impurity 69 (CAS CATO-C4X-240969), a pharmacopoeial impurity reference standard (molecular formula C20H24N2O7S2, MW 468.54 g/mol) used for the identification and quantification of trace impurities in APIs.
Structurally, Lifitegrast Impurity 69 (C20H24N2O7S2) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 468.54 g/mol, it falls into the moderately-high-molecular-weight range. 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.
