Chemical Structure

Terephthalbis(anilide) CAS 14326-69-3 chemical structure

Description

Based on its molecular formula C20H16N2, Terephthalbis(anilide) contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 284.35 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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 Terephthalbis(anilide) (CAS 14326-69-3), a certified reference material (molecular formula C20H16N2, MW 284.35 g/mol) for analytical method development and quality control.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
