Chemical Structure

2,7-Di-tert-butylfluorene 2,7-di-tert-butyl-9H-fluorene 58775-05-6 CAS 58775-05-6 chemical structure

Description

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

CATO supplies 2,7-Di-tert-butylfluorene 2,7-di-tert-butyl-9H-fluorene 58775-05-6 (CAS 58775-05-6), a certified reference material (molecular formula C21H38, MW 290.53 g/mol) for analytical method development and quality control.

Owing to an organic framework, 2,7-Di-tert-butylfluorene 2,7-di-tert-butyl-9H-fluorene 58775-05-6 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 290.53 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.

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.
