Chemical Structure
Description
CATO supplies 2,2,6,6-Tetramethyl-3,5-heptanedionato rubidium (CAS 166439-15-2), a certified reference material (molecular formula C11H22O2Rb, MW 271.76 g/mol) for analytical method development and quality control.
Based on its molecular formula C11H22O2Rb, 2,2,6,6-Tetramethyl-3,5-heptanedionato rubidium contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 271.76 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
