Chemical Structure

Ethyl 5-(bromomethyl)thiophene-3-carboxylate CAS 206860-16-4 chemical structure

Description

The occurrence of Ethyl 5-(bromomethyl)thiophene-3-carboxylate is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Ethyl 5-(bromomethyl)thiophene-3-carboxylate (CAS 206860-16-4) is a high-purity analytical reference standard with the molecular formula C8H9BrO2S and a molecular weight of 249.12 g/mol.

Structurally, Ethyl 5-(bromomethyl)thiophene-3-carboxylate (C8H9BrO2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 249.12 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
