Chemical Structure
Description
(7-bromo-9,9-dimethyl-9H-fluoren-2-yl)(methyl)sulfane (CAS 2764852-69-7), molecular formula C16H15BrS and molecular weight 319.26 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to sulfur-containing functionality, bromine substitution, a polycyclic aromatic system, (7-bromo-9,9-dimethyl-9H-fluoren-2-yl)(methyl)sulfane is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 319.26 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.
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.
