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.
2,2,5,5-Tetramethyltetrahydrofuran (CAS 15045-43-9), molecular formula C8H16O and molecular weight 128.21 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a hydroxyl group, an ether linkage, 2,2,5,5-Tetramethyltetrahydrofuran is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 128.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
