Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
[1,1'-Binaphthalene]-2,2'-diol compound with 4,4'-bipyridine (1:2) (CAS 790229-53-7) is a high-purity analytical reference standard with the molecular formula C20H14O2C10H8N2 and a molecular weight of 442.52 g/mol.
The molecular framework of [1,1'-Binaphthalene]-2,2'-diol compound with 4,4'-bipyridine (1:2) (C20H14O2C10H8N2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. 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).
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.
