Chemical Structure
Description
As a certified reference material (CRM), Vincamine Impurity 1 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.
CATO supplies Vincamine Impurity 1 (CAS 42971-12-0), a pharmacopoeial impurity reference standard (molecular formula C22H26N2O2, MW 350.45 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C22H26N2O2, Vincamine Impurity 1 contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 350.45 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
