Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 9H,9'H-[9,9'-Bifluoren]-9-ol.
9H,9'H-[9,9'-Bifluoren]-9-ol (CAS 981-46-4) is a high-purity analytical reference standard with the molecular formula C15H11N3PtC6H5S and a molecular weight of 537.52 g/mol.
The molecular framework of 9H,9'H-[9,9'-Bifluoren]-9-ol (C15H11N3PtC6H5S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
