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-methyl-4-(phenylthio)pyridinium tetrafluoroborate (CAS 256955-68-7) is a high-purity analytical reference standard with the molecular formula C12H12NSBF4 and a molecular weight of 289.10 g/mol.
The molecular framework of 1-methyl-4-(phenylthio)pyridinium tetrafluoroborate (C12H12NSBF4) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), 1-methyl-4-(phenylthio)pyridinium tetrafluoroborate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
