Chemical Structure
Description
5-(tert-Butyl) 7-methyl 2-oxa-5-azabicyclo[2.2.1]heptane-5,7-dicarboxylate (CAS 1823987-86-5), molecular formula C12H19NO5 and molecular weight 257.28 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 5-(tert-Butyl) 7-methyl 2-oxa-5-azabicyclo[2.2.1]heptane-5,7-dicarboxylate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 257.28 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 5-(tert-Butyl) 7-methyl 2-oxa-5-azabicyclo[2.2.1]heptane-5,7-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.
