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.
Tributyl(2-methoxyethyl)phosphonium Bis(trifluoromethanesulfonyl)imide (CAS 959698-44-3), molecular formula C2F6NO4S2C15H34OP and molecular weight 541.54 g/mol, is a CATO reference standard with documented purity and traceability.
Tributyl(2-methoxyethyl)phosphonium Bis(trifluoromethanesulfonyl)imide (C2F6NO4S2C15H34OP) contains an amide group, a sulfone group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
