Chemical Structure

Triphenylborane - Pyridine Complex CAS 971-66-4 chemical structure

Description

Triphenylborane - Pyridine Complex (CAS 971-66-4), molecular formula C18H15BC5H5N and molecular weight 321.23 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Triphenylborane - Pyridine Complex (C18H15BC5H5N) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
