3,3'-[5'-[4-(3-pyridinyl)phenyl][1,1':3',1''-terphenyl]-4,4''-diyl]bis-Pyridine CAS 921205-02-9

Description

The occurrence of 3,3'-[5'-[4-(3-pyridinyl)phenyl][1,1':3',1''-terphenyl]-4,4''-diyl]bis-Pyridine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3,3'-[5'-[4-(3-pyridinyl)phenyl][1,1':3',1''-terphenyl]-4,4''-diyl]bis-Pyridine (CAS 921205-02-9) is a high-purity analytical reference standard with the molecular formula C39H27N3 and a molecular weight of 537.65 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 3,3'-[5'-[4-(3-pyridinyl)phenyl][1,1':3',1''-terphenyl]-4,4''-diyl]bis-Pyridine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 537.65 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
