Chemical Structure

Cyclopentanone CAS 120-92-3 chemical structure

Description

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.

Cyclopentanone (CAS 120-92-3), molecular formula C5H8O and molecular weight 84.12 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a hydroxyl group, an ether linkage, Cyclopentanone is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 84.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.
