The occurrence of Poly(3-dodecylthiophene-2,5-diyl), regioregular is closely related to sulfur-containing functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Poly(3-dodecylthiophene-2,5-diyl), regioregular (CAS 104934-53-4), molecular formula C16H28S and molecular weight 252.46 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to sulfur-containing functionality, Poly(3-dodecylthiophene-2,5-diyl), regioregular is typically white to off-white low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 252.46 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.
