1,3-Bis(2-aminoethyl)-2-methyl-3-imidazolium Bromide Dihydrobromide (CAS 1156504-76-5), molecular formula C8H17N4HBrBr and molecular weight 330.07 g/mol, is a CATO reference standard with documented purity and traceability.
1,3-Bis(2-aminoethyl)-2-methyl-3-imidazolium Bromide Dihydrobromide (C8H17N4HBrBr) contains bromine substitution. Halogen substitution raises its density and boiling point; 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.
As a certified reference material (CRM), 1,3-Bis(2-aminoethyl)-2-methyl-3-imidazolium Bromide Dihydrobromide 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.
