CATO supplies 1,4-Bis(diphenylphosphino)butane 7688-25-7 1,4-BIS(DIPHENYLPHOSPHINE)BUTANE;1,4-BIS(DIPHENYLPHOSPHINO)BUTANE;1,4-BUTANEDIYLBIS[DIPHENYLPHOSPHINE];1,4-BUTYLENEBIS(DIPHENYLPHOSPHINE);DPPB;TETRAMETHYLENEBIS(DIPHENYLPHOSPHINE);[4-(DIPHENYLPHOSPHANYL)BUTYL]DIPHENYLPHOSPHANE GC10108 (CAS 7688-25-7), a certified reference material (molecular formula C28H52P2, MW 450.66 g/mol) for analytical method development and quality control.
1,4-Bis(diphenylphosphino)butane 7688-25-7 1,4-BIS(DIPHENYLPHOSPHINE)BUTANE;1,4-BIS(DIPHENYLPHOSPHINO)BUTANE;1,4-BUTANEDIYLBIS[DIPHENYLPHOSPHINE];1,4-BUTYLENEBIS(DIPHENYLPHOSPHINE);DPPB;TETRAMETHYLENEBIS(DIPHENYLPHOSPHINE);[4-(DIPHENYLPHOSPHANYL)BUTYL]DIPHENYLPHOSPHANE GC10108 (C28H52P2) contains organophosphorus functionality. 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.
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.
