Chemical Structure
Description
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.
2,2'-(2,5-Bis((2-ethylhexyl)oxy)-1,4-phenylene)dithiophene (CAS 928853-15-0), molecular formula C30H42O2S2 and molecular weight 498.78 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2,2'-(2,5-Bis((2-ethylhexyl)oxy)-1,4-phenylene)dithiophene (C30H42O2S2) contains a steroid core, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 498.78 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
