Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 305.16 g/mol gives 62728-88-5 Rhodium, tetrakis(mu-pentanoato)di- Tetrakis(mu-pentanoato)dirhodium(II) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 62728-88-5 Rhodium, tetrakis(mu-pentanoato)di- Tetrakis(mu-pentanoato)dirhodium(II) (CAS 62728-88-5), a certified reference material (molecular formula C10H18O4Rh, MW 305.16 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 62728-88-5 Rhodium, tetrakis(mu-pentanoato)di- Tetrakis(mu-pentanoato)dirhodium(II) is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 305.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
