5,5'-Di(9H-fluoren-2-yl)-2,2'-bithiophene CAS 369599-41-7 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

5,5'-Di(9H-fluoren-2-yl)-2,2'-bithiophene (CAS 369599-41-7), molecular formula C34H22S2 and molecular weight 494.67 g/mol, is a CATO reference standard with documented purity and traceability.

5,5'-Di(9H-fluoren-2-yl)-2,2'-bithiophene (C34H22S2) contains sulfur-containing functionality, a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
