Dexmedetomidine impurity 62 CAS 19447-06-4 chemical structure

Description

Dexmedetomidine impurity 62 (CAS 19447-06-4) is a certified pharmaceutical impurity reference standard with the molecular formula C10H14O and a molecular weight of 150.22 g/mol.

The molecular framework of Dexmedetomidine impurity 62 (C10H14O) is characterized by a hydroxyl group, an ether linkage, an aromatic ring system. 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), Dexmedetomidine impurity 62 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.
