CATO supplies 2,7-Bis(trimethylstannyl)naphtho[1,2-b:5,6-b']dithiophene (CAS 1218771-02-8), a certified reference material (molecular formula C20H24S2Sn2, MW 565.95 g/mol) for analytical method development and quality control.
Structurally, 2,7-Bis(trimethylstannyl)naphtho[1,2-b:5,6-b']dithiophene (C20H24S2Sn2) contains sulfur-containing functionality, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 565.95 g/mol, it falls into the moderately-high-molecular-weight range. 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.
