Ketoprofen Impurity 80 (Mixture of Diastereomers) CAS 2126161-79-1

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ketoprofen Impurity 80 (Mixture of Diastereomers).

CATO supplies Ketoprofen Impurity 80 (Mixture of Diastereomers) (CAS 2126161-79-1), a pharmacopoeial impurity reference standard (molecular formula C19H20O4, MW 312.36 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Ketoprofen Impurity 80 (Mixture of Diastereomers) (C19H20O4) contains a flavonoid core, 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 312.36 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.

As a certified reference material (CRM), Ketoprofen Impurity 80 (Mixture of Diastereomers) 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.
