Description
CATO supplies 40210-84-2 7,7,8,8-Tetracyanoquinodimethane Tetrathiafulvalene salt TCNQ-TTF TTF-TCNQ Tetrathiafulvalene 7,7,8,8-tetracyanoquinodimethane salt (CAS 40210-84-2), a certified reference material (molecular formula C6H4S4C12H4N4, MW 408.53 g/mol) for analytical method development and quality control.
Structurally, 40210-84-2 7,7,8,8-Tetracyanoquinodimethane Tetrathiafulvalene salt TCNQ-TTF TTF-TCNQ Tetrathiafulvalene 7,7,8,8-tetracyanoquinodimethane salt (C6H4S4C12H4N4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 17.0, corresponding to approximately 17 ring(s) or double-bond equivalent(s). With a molecular weight of 408.53 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
