Chemical Structure

4-(3-Fluorophenyl)cyclohexanone CAS 40503-87-5 chemical structure

Description

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.

4-(3-Fluorophenyl)cyclohexanone (CAS 40503-87-5) is a high-purity analytical reference standard with the molecular formula C12H13FO and a molecular weight of 192.23 g/mol.

Owing to a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 4-(3-Fluorophenyl)cyclohexanone is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 192.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
