Triisobutyl Phosphate CAS 126-71-6

Description

Compared with other compounds in its class, the molecular weight of 266.31 g/mol gives Triisobutyl Phosphate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Triisobutyl Phosphate (CAS 126-71-6), molecular formula C12H27O4P and molecular weight 266.31 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C12H27O4P, Triisobutyl Phosphate contains a phosphate ester group, 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 266.31 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.
