1,1-bis(4-chlorophenyl)-2-{[(3-chlorophenyl)methyl]amino}ethan-1-ol 1J-327S 321432-85-3 (CAS 321432-85-3) is a high-purity analytical reference standard with the molecular formula C21H18Cl3NO and a molecular weight of 406.73 g/mol.
The molecular framework of 1,1-bis(4-chlorophenyl)-2-{[(3-chlorophenyl)methyl]amino}ethan-1-ol 1J-327S 321432-85-3 (C21H18Cl3NO) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), 1,1-bis(4-chlorophenyl)-2-{[(3-chlorophenyl)methyl]amino}ethan-1-ol 1J-327S 321432-85-3 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.
