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.
4-(4-(tert-Butyl)phenyl)-2-methyl-1H-indene (CAS 213381-88-5), molecular formula C20H22 and molecular weight 262.39 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a polycyclic aromatic system, 4-(4-(tert-Butyl)phenyl)-2-methyl-1H-indene is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 262.39 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.
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.
