N-Butyl ethyl sulfide CAS 638-46-0 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.

N-Butyl ethyl sulfide (CAS 638-46-0) is a high-purity analytical reference standard with the molecular formula C6H14S and a molecular weight of 118.24 g/mol.

Owing to sulfur-containing functionality, N-Butyl ethyl sulfide is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 118.24 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.
