Chemical Structure
Description
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.
tert-Butyl 2,7-diazaspiro[4.4]nonane-2-carboxylate oxalate (CAS 2108848-16-2), molecular formula C12H22N2O2C2H2O4 and molecular weight 316.35 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, tert-Butyl 2,7-diazaspiro[4.4]nonane-2-carboxylate oxalate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 316.35 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
