Description
As a certified reference material (CRM), Poly[2,5-bis(3-dodecylthiophen-2-yl)thieno[3,2-b]thiophene] 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.
Poly[2,5-bis(3-dodecylthiophen-2-yl)thieno[3,2-b]thiophene] (CAS 888491-18-7) is a high-purity analytical reference standard with the molecular formula C40H60S4 and a molecular weight of 669.16 g/mol.
Based on its molecular formula C40H60S4, Poly[2,5-bis(3-dodecylthiophen-2-yl)thieno[3,2-b]thiophene] contains sulfur-containing functionality, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 669.16 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
