819050-89-0 Bis[rhodium(|A,|A,|A inverted exclamation marka,|A inverted exclamation marka-tetramethyl-1,3-benzenedipropionic acid)] Rh2(esp)2 (CAS 819050-89-0) is a high-purity analytical reference standard with the molecular formula C16H28O4Rh2 and a molecular weight of 490.22 g/mol.
The molecular framework of 819050-89-0 Bis[rhodium(|A,|A,|A inverted exclamation marka,|A inverted exclamation marka-tetramethyl-1,3-benzenedipropionic acid)] Rh2(esp)2 (C16H28O4Rh2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. 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.
