Chemical Structure

2,2'-Diisopropylbiphenyl CAS 36919-88-7 chemical structure

Description

The occurrence of 2,2'-Diisopropylbiphenyl is closely related to an organic framework in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2,2'-Diisopropylbiphenyl (CAS 36919-88-7), molecular formula C18H34 and molecular weight 250.46 g/mol, is a CATO reference standard with documented purity and traceability.

2,2'-Diisopropylbiphenyl (C18H34) contains an organic framework. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
