Chemical Structure

4-Methyl-9H-fluoren-9-one CAS 4269-05-0 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-Methyl-9H-fluoren-9-one (CAS 4269-05-0) is a high-purity analytical reference standard with the molecular formula C14H10O and a molecular weight of 194.23 g/mol.

Based on its molecular formula C14H10O, 4-Methyl-9H-fluoren-9-one contains a hydroxyl group, an ether linkage, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 194.23 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
