Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 187.28 g/mol gives Pregabalin Impurity 68 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Pregabalin Impurity 68 (CAS 1568110-05-3) is a certified pharmaceutical impurity reference standard with the molecular formula C10H21NO2 and a molecular weight of 187.28 g/mol.
Based on its molecular formula C10H21NO2, Pregabalin Impurity 68 contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 187.28 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), Pregabalin Impurity 68 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.
