【停用见C1650856】Pitolisant Impurity 52 CAS CATO-C4X-252052

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 【停用见C1650856】Pitolisant Impurity 52.

【停用见C1650856】Pitolisant Impurity 52 (CAS CATO-C4X-252052) is a certified pharmaceutical impurity reference standard with the molecular formula C9H9ClO and a molecular weight of 168.62 g/mol.

The molecular framework of 【停用见C1650856】Pitolisant Impurity 52 (C9H9ClO) is characterized by a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, 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), 【停用见C1650856】Pitolisant Impurity 52 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.
