Chemical Structure
Description
As a certified reference material (CRM), Finerenone Impurity 150 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.
Finerenone Impurity 150 (CAS 21962-44-7) is a certified pharmaceutical impurity reference standard with the molecular formula C9H7NO2 and a molecular weight of 161.16 g/mol.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, Finerenone Impurity 150 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 161.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
