CATO supplies 4'-((2-Butyl-4-oxo-1,3-diazaspiro[4.4]non-2-en-1-yl)methyl)-[1,1'-biphenyl]-2-carbonitrile (CAS CATO-C3D-2418), a pharmacopoeial impurity reference standard (molecular formula C25H27N3O, MW 385.50 g/mol) used for the identification and quantification of trace impurities in APIs.
4'-((2-Butyl-4-oxo-1,3-diazaspiro[4.4]non-2-en-1-yl)methyl)-[1,1'-biphenyl]-2-carbonitrile (C25H27N3O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 4'-((2-Butyl-4-oxo-1,3-diazaspiro[4.4]non-2-en-1-yl)methyl)-[1,1'-biphenyl]-2-carbonitrile 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.
