Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 473.93 g/mol gives Lixivaptan - API Standards distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Lixivaptan - API Standards (CAS 168079-32-1) is a high-purity analytical reference standard with the molecular formula C27H21ClFN3O2 and a molecular weight of 473.93 g/mol.
The molecular framework of Lixivaptan - API Standards (C27H21ClFN3O2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine 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).
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), Lixivaptan - API Standards 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.
