2-Butyl-5-propylfuran CAS 67632-31-9

Description

The occurrence of 2-Butyl-5-propylfuran is closely related to a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-Butyl-5-propylfuran (CAS 67632-31-9), molecular formula C11H18O and molecular weight 166.26 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a hydroxyl group, an ether linkage, 2-Butyl-5-propylfuran is typically white to off-white low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 166.26 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.

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.
