pitolisant impurity 2 CAS 64230-79-1

Description

Compared with other compounds in its class, the molecular weight of 242.66 g/mol gives pitolisant impurity 2 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

pitolisant impurity 2 (CAS 64230-79-1) is a certified pharmaceutical impurity reference standard with the molecular formula C11H11ClO4 and a molecular weight of 242.66 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, pitolisant impurity 2 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 242.66 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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), pitolisant impurity 2 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.
