Chemical Structure
Description
The molecular framework of Rel-(2R,3R)-2-benzhydryl-N-(2-iodobenzyl)quinuclidin-3-amine oxalate (C27H29IN2C2H2O4) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, iodine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Rel-(2R,3R)-2-benzhydryl-N-(2-iodobenzyl)quinuclidin-3-amine oxalate (CAS 351351-06-9) is a high-purity analytical reference standard with the molecular formula C27H29IN2C2H2O4 and a molecular weight of 598.48 g/mol.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), Rel-(2R,3R)-2-benzhydryl-N-(2-iodobenzyl)quinuclidin-3-amine oxalate 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.
