1-(2-Acetoxy-2-(3-nitrophenyl)-1-phenylethyl)-2,4-diphenylpyridin-1-ium tetrafluoroborate CAS 80561-20-2 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(2-Acetoxy-2-(3-nitrophenyl)-1-phenylethyl)-2,4-diphenylpyridin-1-ium tetrafluoroborate.

1-(2-Acetoxy-2-(3-nitrophenyl)-1-phenylethyl)-2,4-diphenylpyridin-1-ium tetrafluoroborate (CAS 80561-20-2) is a high-purity analytical reference standard with the molecular formula C33H27N2O4BF4 and a molecular weight of 602.39 g/mol.

The molecular framework of 1-(2-Acetoxy-2-(3-nitrophenyl)-1-phenylethyl)-2,4-diphenylpyridin-1-ium tetrafluoroborate (C33H27N2O4BF4) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

As a certified reference material (CRM), 1-(2-Acetoxy-2-(3-nitrophenyl)-1-phenylethyl)-2,4-diphenylpyridin-1-ium 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.
