Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-methyl-1-(4-methylphenyl)butan-2-one.
3-methyl-1-(4-methylphenyl)butan-2-one (CAS 65248-52-4) is a high-purity analytical reference standard with the molecular formula C12H16O and a molecular weight of 176.25 g/mol.
Owing to a hydroxyl group, an ether linkage, an aromatic ring system, 3-methyl-1-(4-methylphenyl)butan-2-one is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 176.25 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.
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.
