N,N-Dimethyl-4-(2-phenyl-5,10b-dihydro-1H-benzo[e]pyrazolo[1,5-c][1,3]oxazin-5-yl)aniline (CAS 140472-95-3) is a high-purity analytical reference standard with the molecular formula C24H23N3O and a molecular weight of 369.46 g/mol.
The molecular framework of N,N-Dimethyl-4-(2-phenyl-5,10b-dihydro-1H-benzo[e]pyrazolo[1,5-c][1,3]oxazin-5-yl)aniline (C24H23N3O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
As a certified reference material (CRM), N,N-Dimethyl-4-(2-phenyl-5,10b-dihydro-1H-benzo[e]pyrazolo[1,5-c][1,3]oxazin-5-yl)aniline 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.
