Chemical Structure
Description
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.
cis-tert-Butyl 2-oxo-4-phenyl-3-((triethylsilyl)oxy)azetidine-1-carboxylate (CAS 149107-85-7) is a high-purity analytical reference standard with the molecular formula C20H31NO4Si and a molecular weight of 377.55 g/mol.
The molecular framework of cis-tert-Butyl 2-oxo-4-phenyl-3-((triethylsilyl)oxy)azetidine-1-carboxylate (C20H31NO4Si) is characterized by a steroid core, 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. 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).
As a certified reference material (CRM), cis-tert-Butyl 2-oxo-4-phenyl-3-((triethylsilyl)oxy)azetidine-1-carboxylate 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.
