Poly(oxy-1,2-ethanediyl), .alpha.,.alpha.',.alpha.'',.alpha.'''-[[(2-sulfophenyl)methyliumylidene]bis(4,1-phenylenenitrilodi-2,1-ethanediyl)]tetrakis[.omega.-hydroxy-, chloride, sodium salt (1:1:1) (C35H48N2O11SClNa) contains a salt form, a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, 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.
As a certified reference material (CRM), Poly(oxy-1,2-ethanediyl), .alpha.,.alpha.',.alpha.'',.alpha.'''-[[(2-sulfophenyl)methyliumylidene]bis(4,1-phenylenenitrilodi-2,1-ethanediyl)]tetrakis[.omega.-hydroxy-, chloride, sodium salt (1:1:1) meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
