Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including tert-Butyl 5,5,9,9-tetrafluoro-2,7-diazaspiro[3.5]nonane-2-carboxylate.
tert-Butyl 5,5,9,9-tetrafluoro-2,7-diazaspiro[3.5]nonane-2-carboxylate (CAS 1263177-65-6), molecular formula C12H18F4N2O2 and molecular weight 298.28 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C12H18F4N2O2, tert-Butyl 5,5,9,9-tetrafluoro-2,7-diazaspiro[3.5]nonane-2-carboxylate contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 298.28 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
