Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,2',3,3',4',5,5',6,6'-Nonafluoro-[1,1'-biphenyl]-4-amine.
2,2',3,3',4',5,5',6,6'-Nonafluoro-[1,1'-biphenyl]-4-amine (CAS 969-25-5), molecular formula C12H2F9N and molecular weight 331.14 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2,2',3,3',4',5,5',6,6'-Nonafluoro-[1,1'-biphenyl]-4-amine (C12H2F9N) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 331.14 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
