Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-(2-(Thiophen-2-yl)ethyl)-2-azaspiro[4.4]Nonane-1,3-dione (CAS 651292-29-4), molecular formula C14H17NO2S and molecular weight 263.36 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C14H17NO2S, 2-(2-(Thiophen-2-yl)ethyl)-2-azaspiro[4.4]Nonane-1,3-dione contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 263.36 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
