Poly[bis(3-dodecyl-2-thienyl)-2,2'-dithiophene-5,5'-diyl] CAS 827343-06-6

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Poly[bis(3-dodecyl-2-thienyl)-2,2'-dithiophene-5,5'-diyl].

Poly[bis(3-dodecyl-2-thienyl)-2,2'-dithiophene-5,5'-diyl] (CAS 827343-06-6), molecular formula C42H62S4N and molecular weight 709.21 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, Poly[bis(3-dodecyl-2-thienyl)-2,2'-dithiophene-5,5'-diyl] is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 709.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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.
