Chemical Structure
Description
2-Azaspiro[5.5]undecane hemi(oxalic acid) (CAS 2306269-93-0) is a high-purity analytical reference standard with the molecular formula C10H19NC2H2O4 and a molecular weight of 243.30 g/mol.
Based on its molecular formula C10H19NC2H2O4, 2-Azaspiro[5.5]undecane hemi(oxalic acid) 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 243.30 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-Azaspiro[5.5]undecane hemi(oxalic acid) 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.
