Chemical Structure

5-(tert-Butyl)dihydrofuran-3(2H)-one CAS 34003-77-5 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.

5-(tert-Butyl)dihydrofuran-3(2H)-one (CAS 34003-77-5), molecular formula C8H14O2 and molecular weight 142.20 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 5-(tert-Butyl)dihydrofuran-3(2H)-one is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 142.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

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.
