Chemical Structure
Description
As a certified reference material (CRM), 1-tert-Butyl 4-ethyl 6-methyl-5-oxoazepane-1,4-dicarboxylate 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.
1-tert-Butyl 4-ethyl 6-methyl-5-oxoazepane-1,4-dicarboxylate (CAS 884487-29-0), molecular formula C15H25NO5 and molecular weight 299.36 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-tert-Butyl 4-ethyl 6-methyl-5-oxoazepane-1,4-dicarboxylate (C15H25NO5) is characterized by a nitrogen-containing heterocyclic scaffold, 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).
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.
