Chemical Structure

2-(Cyclopentylsulfanyl)-1-phenylethan-1-one CAS 726148-07-8 chemical structure

Description

2-(Cyclopentylsulfanyl)-1-phenylethan-1-one (CAS 726148-07-8), molecular formula C13H16OS and molecular weight 220.33 g/mol, is a CATO reference standard with documented purity and traceability.

2-(Cyclopentylsulfanyl)-1-phenylethan-1-one (C13H16OS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
