CATO supplies (<I>S</I>,<I>S</I>)-2,3-bis(tert-butylmethylphosphino)quinoxaline (CAS 1107608-80-9), a certified reference material (molecular formula C18H38N2P2, MW 344.46 g/mol) for analytical method development and quality control.
Structurally, (<I>S</I>,<I>S</I>)-2,3-bis(tert-butylmethylphosphino)quinoxaline (C18H38N2P2) contains organophosphorus functionality. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 344.46 g/mol, it falls into the moderately-high-molecular-weight range. 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.
