Chemical Structure
Description
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
8-Ethyl-2-azaspiro[4.5]decane-4-carboxylic acid (CAS 1340244-46-3), molecular formula C12H21NO2 and molecular weight 211.30 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, 8-Ethyl-2-azaspiro[4.5]decane-4-carboxylic acid is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 211.30 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.
