2,2′-Benzo[1,2-b:4,5-b′]dithiophene-4,8-diylidenebis[propanedinitrile] CAS 109573-90-2

Description

The occurrence of 2,2′-Benzo[1,2-b:4,5-b′]dithiophene-4,8-diylidenebis[propanedinitrile] is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 2,2′-Benzo[1,2-b:4,5-b′]dithiophene-4,8-diylidenebis[propanedinitrile] (CAS 109573-90-2), a certified reference material (molecular formula C16H4N4S2, MW 316.36 g/mol) for analytical method development and quality control.

The molecular framework of 2,2′-Benzo[1,2-b:4,5-b′]dithiophene-4,8-diylidenebis[propanedinitrile] (C16H4N4S2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
