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.
1,3-Di([2,2’-bithiophen]-5-yl)-1,3-propanedione (CAS 832732-77-1), molecular formula C19H12O2S4 and molecular weight 400.56 g/mol, is a CATO reference standard with documented purity and traceability.
1,3-Di([2,2’-bithiophen]-5-yl)-1,3-propanedione (C19H12O2S4) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
