3,7-Diamino-5-phenylphenazinium chloride 81-93-6 C.I. 50200 NSC-215209 NSC215209 Phenazinium,7-diamino-5-phenyl-, chloride Phenosafranin Phenosafranine Phenosafranine, chloride Phenosafrinine Phenosofranine Phenosofrinine Safranin B Extra Safrinin B Extra Schultz no. 958 WLN: T C666 BK INJ BR& EZ MZ &G WLN: T C666 BK INJ BR& EZ MZ &G &9/26 (CAS 81-93-6) is a high-purity analytical reference standard with the molecular formula C18H34N4Cl and a molecular weight of 341.95 g/mol.
The molecular framework of 3,7-Diamino-5-phenylphenazinium chloride 81-93-6 C.I. 50200 NSC-215209 NSC215209 Phenazinium,7-diamino-5-phenyl-, chloride Phenosafranin Phenosafranine Phenosafranine, chloride Phenosafrinine Phenosofranine Phenosofrinine Safranin B Extra Safrinin B Extra Schultz no. 958 WLN: T C666 BK INJ BR& EZ MZ &G WLN: T C666 BK INJ BR& EZ MZ &G &9/26 (C18H34N4Cl) is characterized by a nitrile group, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
