CATO supplies 25608-63-3 Phenol, 4,4'-sulfonylbis-, polymer with 1,1'-sulfonylbis(4-chlorobenzene) Poly(oxy-1,4-phenylenesulfonyl-1,4-phenylene)-alpha-hydro-omega-hydroxy (CAS 25608-63-3), a certified reference material (molecular formula C12H22O4S, MW 262.37 g/mol) for analytical method development and quality control.
25608-63-3 Phenol, 4,4'-sulfonylbis-, polymer with 1,1'-sulfonylbis(4-chlorobenzene) Poly(oxy-1,4-phenylenesulfonyl-1,4-phenylene)-alpha-hydro-omega-hydroxy (C12H22O4S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
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.
