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-Cyclopentyl-1-(7,7-dimethyl-6,8-dioxa-2-azaspiro[3.5]nonan-2-yl)ethan-1-one (CAS 1396872-18-6), molecular formula C15H25NO3 and molecular weight 267.36 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C15H25NO3, 2-Cyclopentyl-1-(7,7-dimethyl-6,8-dioxa-2-azaspiro[3.5]nonan-2-yl)ethan-1-one contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 267.36 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
