Chemical Structure
Description
As a certified reference material (CRM), 4,8-Bis((2-ethylhexyl)oxy)benzo[1,2-b:4,5-b']dithiophene meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
4,8-Bis((2-ethylhexyl)oxy)benzo[1,2-b:4,5-b']dithiophene (CAS 1160823-77-7) is a high-purity analytical reference standard with the molecular formula C26H38O2S2 and a molecular weight of 446.71 g/mol.
4,8-Bis((2-ethylhexyl)oxy)benzo[1,2-b:4,5-b']dithiophene (C26H38O2S2) contains a steroid core, a sulfone group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
