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 4-Fluoro-[1,1'-biphenyl]-3-amine.
4-Fluoro-[1,1'-biphenyl]-3-amine (CAS 478403-55-3) is a high-purity analytical reference standard with the molecular formula C12H10FN and a molecular weight of 187.21 g/mol.
Based on its molecular formula C12H10FN, 4-Fluoro-[1,1'-biphenyl]-3-amine contains a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 187.21 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
