Chemical Structure
Description
As a certified reference material (CRM), Tert-butyl (S)-(3-oxo-1-phenylbutan-2-yl)carbamate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
Tert-butyl (S)-(3-oxo-1-phenylbutan-2-yl)carbamate (CAS 85613-64-5), molecular formula C15H21NO3 and molecular weight 263.33 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Tert-butyl (S)-(3-oxo-1-phenylbutan-2-yl)carbamate (C15H21NO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 263.33 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.
