Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 1thia-2-azaspiro[4.4]nonane 1,1-dioxide is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 175.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
1thia-2-azaspiro[4.4]nonane 1,1-dioxide (CAS 1547005-85-5), molecular formula C7H13NO2S and molecular weight 175.25 g/mol, is a CATO reference standard with documented purity and traceability.
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.
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.
