Chemical Structure

2,7-di-tert-butyl-9-fluorenylmethanol CAS 136453-59-3 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.

CATO supplies 2,7-di-tert-butyl-9-fluorenylmethanol (CAS 136453-59-3), a certified reference material (molecular formula C22H40O, MW 320.55 g/mol) for analytical method development and quality control.

Owing to a hydroxyl group, an ether linkage, 2,7-di-tert-butyl-9-fluorenylmethanol is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 320.55 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.
