Chemical Structure
Description
The occurrence of 3-Methyl-9H-fluoren-9-one is closely related to a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-Methyl-9H-fluoren-9-one (CAS 1705-89-1) is a high-purity analytical reference standard with the molecular formula C14H10O and a molecular weight of 194.23 g/mol.
Owing to a hydroxyl group, an ether linkage, a polycyclic aromatic system, 3-Methyl-9H-fluoren-9-one is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 194.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
CATO manufactures 3-Methyl-9H-fluoren-9-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
