Chemical Structure

2-Ethylbutanethioamide CAS 98278-52-5 chemical structure

Description

2-Ethylbutanethioamide (CAS 98278-52-5), molecular formula C6H13NS and molecular weight 131.24 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to sulfur-containing functionality, 2-Ethylbutanethioamide is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 131.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
