Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 9,9-Difluoro-3-azaspiro[5.5]Undecane.
9,9-Difluoro-3-azaspiro[5.5]Undecane (CAS 1781297-83-3) is a high-purity analytical reference standard with the molecular formula C10H17F2N and a molecular weight of 189.25 g/mol.
Structurally, 9,9-Difluoro-3-azaspiro[5.5]Undecane (C10H17F2N) contains a nitrile group, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 189.25 g/mol, it falls into the medium-molecular-weight range. 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.
