Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-benzyl-2-ethyl-4,6-diphenylpyridinium tetrafluoroborate.
1-benzyl-2-ethyl-4,6-diphenylpyridinium tetrafluoroborate (CAS 828940-79-0) is a high-purity analytical reference standard with the molecular formula C26H24NBF4 and a molecular weight of 437.29 g/mol.
The molecular framework of 1-benzyl-2-ethyl-4,6-diphenylpyridinium tetrafluoroborate (C26H24NBF4) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, fluorine substitution. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
