Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 177.06 g/mol gives 3-(Bromomethyl)thiophene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-(Bromomethyl)thiophene (CAS 34846-44-1), molecular formula C5H5BrS and molecular weight 177.06 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3-(Bromomethyl)thiophene (C5H5BrS) contains sulfur-containing functionality, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 177.06 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.
