Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 326.82 g/mol gives rac- Etomoxir distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies rac- Etomoxir (CAS 82258-36-4), a certified reference material (molecular formula C17H23ClO4, MW 326.82 g/mol) for analytical method development and quality control.
The molecular framework of rac- Etomoxir (C17H23ClO4) is characterized by a steroid core, 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.
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), rac- Etomoxir 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.
