Chemical Structure
Description
1-Cyclopentyl-4-methylbenzene (CAS 827-55-4) is a high-purity analytical reference standard with the molecular formula C12H16 and a molecular weight of 160.26 g/mol.
Owing to an aromatic ring system, 1-Cyclopentyl-4-methylbenzene is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 160.26 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
