Chemical Structure

914777-33-6
Oxazolidinone Dimer Impurity CAS 914777-33-6 chemical structure

Description

Owing to a steroid core, a hydroxyl group, an ether linkage, fluorine substitution, 914777-33-6 Oxazolidinone Dimer Impurity is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 358.38 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

914777-33-6 Oxazolidinone Dimer Impurity (CAS 914777-33-6), molecular formula C21H20F2O3 and molecular weight 358.38 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.
