Chemical Structure

3-(butan-2-yl)cyclopentan-1-one CAS 91523-76-1 chemical structure

Description

The occurrence of 3-(butan-2-yl)cyclopentan-1-one is closely related to a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-(butan-2-yl)cyclopentan-1-one (CAS 91523-76-1), molecular formula C9H16O and molecular weight 140.22 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C9H16O, 3-(butan-2-yl)cyclopentan-1-one contains a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 140.22 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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.
