Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Tert-butyl (R)-8-amino-5-oxa-2-azaspiro[3.4]Octane-2-carboxylate (CAS 2198241-64-2) is a high-purity analytical reference standard with the molecular formula C11H20N2O3 and a molecular weight of 228.29 g/mol.
The molecular framework of Tert-butyl (R)-8-amino-5-oxa-2-azaspiro[3.4]Octane-2-carboxylate (C11H20N2O3) is characterized by an amino-acid-derived structure, 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), Tert-butyl (R)-8-amino-5-oxa-2-azaspiro[3.4]Octane-2-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.
