Chemical Structure

Ethyl 4-Bromobutyrate CAS 2969-81-5 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.

Ethyl 4-Bromobutyrate (CAS 2969-81-5) is a high-purity analytical reference standard with the molecular formula C6H11BrO2 and a molecular weight of 195.05 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, Ethyl 4-Bromobutyrate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 195.05 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
