Compared with other compounds in its class, the molecular weight of 134.14 g/mol gives Pramipexole Impurity 14 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Pramipexole Impurity 14 (CAS 4570-41-6) is a certified pharmaceutical impurity reference standard with the molecular formula C7H6N2O and a molecular weight of 134.14 g/mol.
Owing to an amide group, a hydroxyl group, an ether linkage, an aromatic ring system, Pramipexole Impurity 14 is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 134.14 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), Pramipexole Impurity 14 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.
