2650-17-1 Sodium hydrogen 4-((4-(ethylamino)-m-tolyl)(4-(ethylimino)-3-methylcyclohexa-2,5-dien-1-ylidene)methyl)benzene-1,3-disulphonate 1,3-Benzenedisulfonic acid, 4-((4-(ethylamino)-3-methylphenyl)(4-(ethylimino)-3-methyl-2,5-cyclohexadien-1-ylidene)methyl)-, sodium salt (1:1) 1,3-Benzenedisulfonic acid, 4-((4-(ethylamino)-3-methylphenyl)(4-(ethylimino)-3-methyl-2,5-cyclohexadien-1-ylidene)methyl)-, monosodium salt EINECS 220-167-5 (C25H39N2O6S2Na) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
