Chemical Structure

Bis(pyridin-4-ylthio)methane CAS 91091-06-4 chemical structure

Description

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.

Bis(pyridin-4-ylthio)methane (CAS 91091-06-4), molecular formula C11H10N2S2 and molecular weight 234.34 g/mol, is a CATO reference standard with documented purity and traceability.

Bis(pyridin-4-ylthio)methane (C11H10N2S2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
