Chemical Structure
Description
The occurrence of 9-Methyl-9-phenylfluorene is closely related to a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
9-Methyl-9-phenylfluorene (CAS 56849-83-3), molecular formula C20H16 and molecular weight 256.34 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a polycyclic aromatic system, 9-Methyl-9-phenylfluorene is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 256.34 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).
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 9-Methyl-9-phenylfluorene 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.
