Chemical Structure
Description
The molecular framework of rel-tert-Butyl ((R)-1-((S)-oxiran-2-yl)-2-phenylethyl)carbamate (C15H21NO3) is characterized by a nitrogen-containing heterocyclic scaffold, 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.
rel-tert-Butyl ((R)-1-((S)-oxiran-2-yl)-2-phenylethyl)carbamate (CAS 98818-35-0), molecular formula C15H21NO3 and molecular weight 263.33 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.
