Chemical Structure
Description
The molecular framework of (R)-5-(7-(4-(4-Ethyl-4,5-dihydrooxazol-2-yl)phenoxy)heptyl)-3-methylisoxazole (C22H30N2O3) 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 the protonation state of its nitrogen-containing groups, 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.
(R)-5-(7-(4-(4-Ethyl-4,5-dihydrooxazol-2-yl)phenoxy)heptyl)-3-methylisoxazole (CAS 112270-40-3), molecular formula C22H30N2O3 and molecular weight 370.49 g/mol, is a CATO reference standard with documented purity and traceability.
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.
