Chemical Structure
Description
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.
(S)-5-(7-(4-(4-Ethyl-4,5-dihydrooxazol-2-yl)phenoxy)heptyl)-3-methylisoxazole (CAS 112270-39-0) is a high-purity analytical reference standard with the molecular formula C22H30N2O3 and a molecular weight of 370.49 g/mol.
The molecular framework of (S)-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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
