Chemical Structure
Description
CATO supplies 2,5-Bis(2-thienyl)-3,4-diaminothiophene (CAS 185691-91-2), a certified reference material (molecular formula C12H10N2S3, MW 278.42 g/mol) for analytical method development and quality control.
The molecular framework of 2,5-Bis(2-thienyl)-3,4-diaminothiophene (C12H10N2S3) 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 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.
