(4R)-3-(1-Oxo-4-penten-1-yl)-4-(phenylmethyl)-2-oxazolidinone (CAS 155399-10-3), molecular formula C15H17NO3 and molecular weight 259.30 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (4R)-3-(1-Oxo-4-penten-1-yl)-4-(phenylmethyl)-2-oxazolidinone (C15H17NO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 259.30 g/mol, it falls into the medium-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
