Loxoprofen Impurity 6 CAS CATO-C4X-14886

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Loxoprofen Impurity 6.

CATO supplies Loxoprofen Impurity 6 (CAS CATO-C4X-14886), a pharmacopoeial impurity reference standard (molecular formula C18H24O4, MW 304.39 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Loxoprofen Impurity 6 (C18H24O4) is characterized by a flavonoid core, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), Loxoprofen Impurity 6 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.
