Chemical Structure
Description
The molecular framework of 5-N-Octyl-2-[4-(N-octyloxy)-phenyl]-pyrimidine 5-octyl-2-(4-(octyloxy)phenyl)pyrimidine 57202-50-3 (C26H40N2O) 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. 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).
CATO supplies 5-N-Octyl-2-[4-(N-octyloxy)-phenyl]-pyrimidine 5-octyl-2-(4-(octyloxy)phenyl)pyrimidine 57202-50-3 (CAS 57202-50-3), a certified reference material (molecular formula C26H40N2O, MW 396.61 g/mol) for analytical method development and quality control.
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.
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.
