[2,2':5',2''-Terthiophene]-5,5''-dicarbaldehyde CAS 13130-50-2

Description

CATO supplies [2,2':5',2''-Terthiophene]-5,5''-dicarbaldehyde (CAS 13130-50-2), a certified reference material (molecular formula C14H8O2S3, MW 304.41 g/mol) for analytical method development and quality control.

Structurally, [2,2':5',2''-Terthiophene]-5,5''-dicarbaldehyde (C14H8O2S3) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 304.41 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.

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.
