The molecular framework of 139-93-5 8BAJ8WP85I Arsphenamine Arsphenamine [USP] 6,6'-Dihydroxy-3,3'-diarsene-1,2-diyldianilinium dichloride Phenol, 4,4'-arsenobis(2-amino-, dihydrochloride Phenol, 4,4'-(1,2-diarsenediyl)bis(2-amino-, dihydrochloride (9CI) X 109 Arsabenzosol Arsaminol Arsenobenzene, 3,3'-diamino-4,4'-dihydroxy-, dihydrochloride Arsenobenzol dihydrochloride Arsenphenolamine hydrochloride Arsfenamin [Czech] 3,3'-Diamino-4,4'-dihydroxyarsenobenzene dihydrochloride 4,4'-(1,2-Diarsenediyl)bis(2-aminophenol) dihydrochloride Diarsenol Ehrlich 606 EINECS 205-386-6 Eparsenol Kharsivan Novarsol NSC 3097 Phenarsenamine Phenol, 4,4'-arsenobis(2-amino- Salavarsan Salvarsan Sanluol Six hundred six Tanvarsan Arsfenamin UNII-8BAJ8WP85I (C12H14As2N2O2Cl) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
