1-(2,5-Dimethylphenyl)-2-(propylthio)ethan-1-one CAS 1157206-30-8

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(2,5-Dimethylphenyl)-2-(propylthio)ethan-1-one.

1-(2,5-Dimethylphenyl)-2-(propylthio)ethan-1-one (CAS 1157206-30-8) is a high-purity analytical reference standard with the molecular formula C13H18OS and a molecular weight of 222.35 g/mol.

Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system, 1-(2,5-Dimethylphenyl)-2-(propylthio)ethan-1-one is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 222.35 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.
