Chemical Structure

2-Cyclopropyl-2-methylcyclobutanone CAS 42436-84-0 chemical structure

Description

2-Cyclopropyl-2-methylcyclobutanone (CAS 42436-84-0) is a high-purity analytical reference standard with the molecular formula C8H12O and a molecular weight of 124.18 g/mol.

Owing to a hydroxyl group, an ether linkage, 2-Cyclopropyl-2-methylcyclobutanone is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 124.18 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).

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.
