Chemical Structure
Description
CATO supplies tert-Butyl ((3R)-2-oxoazepan-3-yl)carbamate (CAS 106691-72-9), a certified reference material (molecular formula C11H20N2O3, MW 228.29 g/mol) for analytical method development and quality control.
Based on its molecular formula C11H20N2O3, tert-Butyl ((3R)-2-oxoazepan-3-yl)carbamate contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 228.29 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
As a certified reference material (CRM), tert-Butyl ((3R)-2-oxoazepan-3-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.
