The occurrence of Diisopropylbenzene(mixture of isomers) is closely related to an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Diisopropylbenzene(mixture of isomers) (CAS 25321-09-9), a certified reference material (molecular formula C9H12, MW 120.19 g/mol) for analytical method development and quality control.
Owing to an aromatic ring system, Diisopropylbenzene(mixture of isomers) is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 120.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
