Chemical Structure
Description
The occurrence of (4R,5R)-tert-Butyl 4-cyano-2,2,5-trimethyloxazolidine-3-carboxylate is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(4R,5R)-tert-Butyl 4-cyano-2,2,5-trimethyloxazolidine-3-carboxylate (CAS 943147-84-0) is a high-purity analytical reference standard with the molecular formula C12H20N2O3 and a molecular weight of 240.30 g/mol.
Structurally, (4R,5R)-tert-Butyl 4-cyano-2,2,5-trimethyloxazolidine-3-carboxylate (C12H20N2O3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 240.30 g/mol, it falls into the medium-molecular-weight range. 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).
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.
