Chemical Structure

9-Phenylfluorene CAS 789-24-2 chemical structure

Description

The occurrence of 9-Phenylfluorene is closely related to a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 9-Phenylfluorene (CAS 789-24-2), a certified reference material (molecular formula C19H14, MW 242.31 g/mol) for analytical method development and quality control.

Structurally, 9-Phenylfluorene (C19H14) contains a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 242.31 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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

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.
