Chemical Structure
Description
As a certified reference material (CRM), Lasofoxifene 2-Oxide 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.
Lasofoxifene 2-Oxide (CAS 366017-88-1), molecular formula C28H29NO3 and molecular weight 427.53 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Lasofoxifene 2-Oxide (C28H29NO3) 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.
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.
