Chemical Structure
Description
Owing to a polycyclic aromatic system, 4-(2-Biphenyl)-2-methyl-1-butene is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 222.32 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO supplies 4-(2-Biphenyl)-2-methyl-1-butene (CAS 951890-11-2), a certified reference material (molecular formula C17H18, MW 222.32 g/mol) for analytical method development and quality control.
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.
