Chemical Structure

N,N'-(Thieno[3,2-b]thiophene-2,5-diylidene)dicyanamide CAS 125594-14-1 chemical structure

Description

CATO supplies N,N'-(Thieno[3,2-b]thiophene-2,5-diylidene)dicyanamide (CAS 125594-14-1), a certified reference material (molecular formula C8H2N4S2, MW 218.26 g/mol) for analytical method development and quality control.

The molecular framework of N,N'-(Thieno[3,2-b]thiophene-2,5-diylidene)dicyanamide (C8H2N4S2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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).

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

As a certified reference material (CRM), N,N'-(Thieno[3,2-b]thiophene-2,5-diylidene)dicyanamide meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
