Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine substitution, 2-[(3,4,4-Trifluorobut-3-en-1-yl)sulfanyl]quinoxaline is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 270.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO supplies 2-[(3,4,4-Trifluorobut-3-en-1-yl)sulfanyl]quinoxaline (CAS 148515-90-6), a certified reference material (molecular formula C12H9F3N2S, MW 270.27 g/mol) for analytical method development and quality control.
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.
