Compared with other compounds in its class, the molecular weight of 182.28 g/mol gives 1-[5-(2-Methylpropyl)thiophen-2-yl]ethan-1-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-[5-(2-Methylpropyl)thiophen-2-yl]ethan-1-one (CAS 84702-96-5) is a high-purity analytical reference standard with the molecular formula C10H14OS and a molecular weight of 182.28 g/mol.
Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system, 1-[5-(2-Methylpropyl)thiophen-2-yl]ethan-1-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 182.28 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.
