Chemical Structure
Description
The molecular framework of Rel-(R)-4-((R)-sec-butyl)oxazolidine-2,5-dione (C7H11NO3) is characterized by an amino-acid-derived structure, 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. 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-(R)-4-((R)-sec-butyl)oxazolidine-2,5-dione (CAS 51829-75-5) is a high-purity analytical reference standard with the molecular formula C7H11NO3 and a molecular weight of 157.17 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
