Compared with other compounds in its class, the molecular weight of 208.32 g/mol gives 4-((Cyclopentyloxy)methyl)benzenethiol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
4-((Cyclopentyloxy)methyl)benzenethiol (CAS 1379348-23-8) is a high-purity analytical reference standard with the molecular formula C12H16OS and a molecular weight of 208.32 g/mol.
Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system, 4-((Cyclopentyloxy)methyl)benzenethiol is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 208.32 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.
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.
