Bis(2-ethylhexyl) dodecanedioate CAS 19074-24-9

Description

Compared with other compounds in its class, the molecular weight of 454.73 g/mol gives Bis(2-ethylhexyl) dodecanedioate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Bis(2-ethylhexyl) dodecanedioate (CAS 19074-24-9), a certified reference material (molecular formula C28H54O4, MW 454.73 g/mol) for analytical method development and quality control.

Based on its molecular formula C28H54O4, Bis(2-ethylhexyl) dodecanedioate 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 454.73 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.

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.
